## Description: The mission of Drill is the creation and maintenance of software related to Schema-free SQL Query Engine for Apache Hadoop, NoSQL and Cloud Storage ## Project Status: Current project status: Ongoing Issues for the board: No issues requiring board attention. ## Membership Data: Apache Drill was founded 2014-11-18 (9 years ago) There are currently 62 committers and 27 PMC members in this project. The Committer-to-PMC ratio is roughly 2:1. Community changes, past quarter: - No new PMC members. Last addition was James Turton on 2022-01-23. - No new committers. Last addition was Maksym Rymar on 2022-10-19. ## Project Activity: We are overdue for the release od Drill 1.21.2 AND 1.22.0. Regarding the minor release, we had a license file issue which took some time to resolve and then we've had a number of recent bug submissions which were promptly fixed. I would anticipate 1.21.1 being released before the end of the month. For 1.22, we have been collaborating with the Mike Bekerle from Daffodil. The goal is to use Apache Daffodil to provide schema information to Drill for querying non-traditional files. We're waiting for the release of Daffodil 3.7 which has some functionalities that we need for the integration. Hopefully this month or next we will be able to complete this work. Recent releases: 1.21.1 was released on 2023-04-29. 1.21.0 was released on 2023-02-21. 1.20.3 was released on 2023-01-07. ## Community Health: The Drill community remains healthy. dev@drill.apache.org had a 112% increase in traffic in the past quarter (323 emails compared to 152) issues@drill.apache.org had a 186% increase in traffic in the past quarter (278 emails compared to 97) user@drill.apache.org had a 76% decrease in traffic in the past quarter (6 emails compared to 25) 33 commits in the past quarter (65% increase) 10 code contributors in the past quarter (42% increase) 21 PRs opened on GitHub, past quarter (16% increase) 22 PRs closed on GitHub, past quarter (46% increase) 10 issues opened on GitHub, past quarter (-9% change) 2 issues closed on GitHub, past quarter (-33% change)

We are planning a maintenance release (v 1.21.2) which we will release before the end of the year. Additionally, for the last few months, we have been collaborating with Mike Bekerle from the Apache Daffodil project. The goal being to enable Drill to use Daffodil schemata to read and parse data. We are maybe 60% complete with this task. This also has a dependency on Apache Daffodil as Mike is developing some custom features for Daffodil. Big thanks to Mike for taking on this project. ## Community Health: Overall the community is healthy. We are working on some major improvements such as the Daffodil integration and an XSD reader so the total number of tickets is lower this quarter. * 11 issues opened in JIRA, past quarter (-21% change) * 10 issues closed in JIRA, past quarter (150% increase) * 20 commits in the past quarter (-20% change) * 7 code contributors in the past quarter (-12% change) * 18 PRs opened on GitHub, past quarter (38% increase) * 15 PRs closed on GitHub, past quarter (15% increase) * 11 issues opened on GitHub, past quarter (57% increase) * 3 issues closed on GitHub, past quarter (-25% change)

## Description: The mission of Drill is the creation and maintenance of software related to Schema-free SQL Query Engine for Apache Hadoop, NoSQL and Cloud Storage ## Issues: No issues requriing Board attention. The PMC would like to express a little disappointment with the rather tepid response to our request for a release announcement. Drill 1.21 was a very significant release from a functionality perspective, and the only announcements we received were buried in other announcements. ## Membership Data: Apache Drill was founded 2014-11-18 (8 years ago) There are currently 62 committers and 27 PMC members in this project. The Committer-to-PMC ratio is roughly 2:1. Community changes, past quarter: - No new PMC members. Last addition was James Turton on 2022-01-23. - No new committers. Last addition was Maksym Rymar on 2022-10-19. ## Project Activity: Since the last report, we released Drill 1.21.0 and a bugfix release of 1.21.1. 1.21 was quite a significant release in that we eliminated the fork of Apache Calcite that Drill was using and now Drill is running on the main branch of Calcite, 1.34. The result was a significant improvement in stability and overall ease of use. Another very significant improvement was the work done to improve implicit casting. One of the main challenges of Drill was querying data without a schema. When it works, the exprience is magical, but when it doesn't, the user was often confronted with a barrage of incomprehensible errors Drill 1.21.0 largely fixes both of these issues and by in large, "it just works"! Drill 1.21 also adds new connectors/plugins for: * GoogleSheets * Box File System * MS Access Drill 1.21 also adds the ability for Drill to query other Drill clusters. This is particularly useful if a user has data in multiple public clouds. In this scenario, Drill can be installed in both environments, and then connected using the new Drill-on-Drill plugin. From there, a user can query across environments without incurring massive data transfer costs. Lastly, Drill 1.21 user translation to the security settings. User translation allows users to use individual credentials instead of service accounts to query data in systems like Splunk or ElasticSearch. 1.21.1 is a minor bugfix release which fixed a significant regression in Calcite's date functions as well as some other minor bugs. 1.21.1 was released on 2023-04-29. 1.21.0 was released on 2023-02-21. 1.20.3 was released on 2023-01-07. ## Community Health: Drill's community health remains strong. dev@drill.apache.org had a 4% increase in traffic in the past quarter (349 emails compared to 335) issues@drill.apache.org had a 52% increase in traffic in the past quarter (495 emails compared to 324) 29 issues opened in JIRA, past quarter (-32% change) 35 issues closed in JIRA, past quarter (-7% change) 112 commits in the past quarter (13% increase) 11 code contributors in the past quarter (-8% change) 34 PRs opened on GitHub, past quarter (-20% change) 34 PRs closed on GitHub, past quarter (-27% change) 11 issues opened on GitHub, past quarter (37% increase) 4 issues closed on GitHub, past quarter (33% increase)

Last addition was Maksym Rymar on 2022-10-19. ## Project Activity: We recently released a bug-fix release, 1.20.3 in early January. We are 2 PRs away from beginning the release process for Drill 1.21. Drill 1.21 is a very significant release for Drill. New features include: * Format readers for Apache Iceberg, Delta Lake, and MS Access. * Storage Plugins (Connectors) for GoogleSheets * We've also added a storage plugin to allow Drill to connect to other Drill clusters. This enables efficient cross-cloud queries. * Until Drill 1.21, Drill had been using a fork of Calcite. For Drill 1.21, we have eliminated this and Drill is now running on the latest version of Calcite. When we merged this, we were able to close numerous bug reports. There are numerous stability improvements as well. * Support for PIVOT, UNPIVOT, REGR_SLOPE and many other operators. * Improved implicit casting rules which dramatically reduce the number of schema change exceptions * We've implemented user translation which allows users to use individual credentials in the various storage plugins. Of the storage plugins that have individual credentials, only MongoDB remains to be updated to support user translation * Support for INSERT. Drill now supports INSERT operations for JDBC data sources, Splunk, and GoogleSheets * Write capability has also been extended to many of the storage plugins. Recent releases: 1.20.3 was released on 2023-01-07. 1.20.2 was released on 2022-08-03. 1.20.1 was released on 2022-05-16. ## Community Health: The Drill community remains small but strong. dev@drill.apache.org had a 80% increase in traffic in the past quarter (1147 emails compared to 635) issues@drill.apache.org had a 79% increase in traffic in the past quarter (1033 emails compared to 576) 37 issues opened in JIRA, past quarter (-53% change) 37 issues closed in JIRA, past quarter (-42% change) 93 commits in the past quarter (-15% change) 12 code contributors in the past quarter (-20% change) 38 PRs opened on GitHub, past quarter (-50% change) 39 PRs closed on GitHub, past quarter (-52% change) 8 issues opened on GitHub, past quarter (-11% change) 3 issues closed on GitHub, past quarter (-62% change)

Additionally, we will begin discussions for the release of Drill 2.0. Drill 2.0 will have significant improvements over Drill 1.x including: ### New Data Formats * GoogleSheets * Apache Phoenix * Delta Lake * Apache Iceberg ### Calcite Upgrade Most significantly, 2.0 dispenses with the need for Drill to maintain a fork of Apache Calcite. Drill 2.0 is now running on the latest version of Calcite which has enabled us to close numerous query planning bugs. Additionally query planning performance is approximately 30-40% faster than with the old fork. ### Security Improvements Drill 2.0 also introduces the concept of user-translation which allows users to use their own credentials when querying external, non-file based storage. ### Other Improvements There are other significant improvements, but one of the most signficant is the refactoring of Drill's implicit casting which makes it so that Drill queries fail much less frequently due to schema change exceptions. 1.20.2 was released on 2022-08-03. 1.20.1 was released on 2022-05-16. 1.20.0 was released on 2022-02-25. 1.19.0 was released on 2021-06-10. ## Community Health: The Drill community remains healthy.

## Project Activity:
Drill 1.20.2 was released on August 3rd. This is a largely bugfix release and
complete release notes are available here:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&version=12351742
Also of note is that the Drill community is working on Drill 2.0 which will
have significant improvements from Drill 1.XX. Thanks to Vova Vystoskyi, we
recently merged a very significant pull request. For the last three years,
Drill has been using a fork of Calcite, which effectively meant that we were
stuck with a rapidly aging version of Calcite. More importantly was that
we were missing out on the last three years of bug fixes and performance
improvements in Calcite. A few weeks ago, we merged this pull request and we
are seeing significant performance improvements.
James Turton did some initial benchmarks on the TPC-H queries and found that
Drill with the new Calcite is about 50% faster than Drill with the old version
of Calcite.

## Description: The mission of Drill is the creation and maintenance of software related to Schema-free SQL Query Engine for Apache Hadoop, NoSQL and Cloud Storage ## Issues: No significant issues to report. ## Membership Data: Apache Drill was founded 2014-11-18 (7 years ago) There are currently 61 committers and 27 PMC members in this project. The Committer-to-PMC ratio is roughly 2:1. Community changes, past quarter: - No new PMC members. Last addition was James Turton on 2022-01-23. - Tengfei Wang was added as committer on 2022-02-22 ## Project Activity: The Drill project released a bug fix release on May 16, 2022. The bug fix release deals with a number of critical CVEs. Release notes will be published shortly. * 1.20.1 was released on 2022-05-16. * 1.20.0 was released on 2022-02-25. * 1.19.0 was released on 2021-06-10. Conversations continue about Drill 2.0. We have merged a very significant improvement which we are calling user translation. Currently, Drill can impersonate a user for file systems, however for connections to data sources which do not have the concept of user impersonation. For instance, relational databases generally require usernames and passwords. Prior to these mods Drill would only allow one set of shared credentials for these plugins. With user translation, users must supply their own individual credentials for all plugins. This option is configurable for each plugin, so users can still use a shared user or user translation. Another area of ongoing work for Drill 2.0 is to eliminate the need for Drill to maintain our own fork of Calcite. The unfortunate result of this has been that Drill is stuck on a version of Calcite that is several years old and not benefiting from all the work that is going on in the Calcite community. This is ongoing work. ## Community Health: The Drill community health is strong. What isn't reflected in the metrics below are the complexity of some of the pull requests which were merged, particularly those around access controls. * dev@drill.apache.org had a 80% increase in traffic in the past quarter (1147 emails compared to 635) * issues@drill.apache.org had a 79% increase in traffic in the past quarter (1033 emails compared to 576) * 82 issues opened in JIRA, past quarter (-14% change) * 37 issues closed in JIRA, past quarter (-59% change) * 113 commits in the past quarter (-16% change) * 20 code contributors in the past quarter (-4% change) * 83 PRs opened on GitHub, past quarter (-3% change) * 81 PRs closed on GitHub, past quarter (-8% change) * 3 issues opened on GitHub, past quarter (-80% change) * 4 issues closed on GitHub, past quarter (-60% change) * 375 users on the Apache Drill slack channel.
## Description: The mission of Drill is the creation and maintenance of software related to Schema-free SQL Query Engine for Apache Hadoop, NoSQL and Cloud Storage ## Issues: No blocking issues. ## Membership Data: Apache Drill was founded 2014-11-18 (7 years ago) There are currently 60 committers and 27 PMC members in this project. The Committer-to-PMC ratio is roughly 5:3. Community changes, past quarter: - James Turton was added to the PMC on 2022-01-23 - PJ Fanning was added as committer on 2022-01-19 ## Project Activity: The Drill team is preparing to release Drill 1.20. We released RC0 for Drill 1.20 on 5 February. One minor bug was found, so we will likely be putting out RC1 shortly. Drill 1.20 is significant in that in addition to new functionality and bug fixes the new version has backwards compatibility with Hadoop 2. This limitation meant that many organizations could not upgrade past Drill circa 1.17. Some highlights of Drill 1.20 are: * Storage plugin for Apache Phoenix * Format plugin for Apache Iceberg * Upgrade Parquet reader to Parquet v2 * Support for automatic de-pagination for REST plugin * Support for OAuth2.0 for REST queries * Refactoring pushdowns for Mongo much more... The Drill community has been holding monthly hangout meetings which James Turton has organized. We've been discussing building a Drill 2.0 and what that would entail. There are a few key themes of things which we should revise which would necessarily break some existing functionality. * 1.19.0 was released on 2021-06-10. * 1.18.0 was released on 2020-09-04. * 1.17.0 was released on 2019-12-26. ## Community Health: The Drill community is growing and I would say strong.

Drill's most recent release was featured in VentureBeat and a few other tech publications! Drill will be targeting to release our next version in the fall, exact timing is TBD. We have a few large pull requests in flight which will add significant functionality in Drill. The first is DRILL-7985 [1] which refactors Drill's pushdown API. The effect of this is that it will be easier to write storage plugins and it will be possible and easier to add more optimizations to existing plugins. This PR has one approval and is likely to be committed in the next few days. Another very significant addition to Drill is DRILL-7871 [2] which enables access controls around storage plugin configurations. This is the first step towards making Drill truly multi-tenant. [1]: https://github.com/apache/drill/pull/2289 [2]: https://github.com/apache/drill/pull/2251 ## Community Health: Community health remains strong. Some of the recent pull requests are much more complex, so as a result we are seeing fewer pull requests. Drill is transitioning to using github Issues as well as our Slack channel. For the next quarterly report, I will see how I can gather Slack metrics and include them as well. (Slack limits the data for unpaid plans unfortunately) * dev@drill.apache.org had a 11% decrease in traffic in the past quarter (668 emails compared to 746) * 41 issues opened in JIRA, past quarter (-45% change) * 16 issues closed in JIRA, past quarter (-75% change) * 201 commits in the past quarter (89% increase) * 18 code contributors in the past quarter (-10% change) * 49 PRs opened on GitHub, past quarter (-30% change) * 47 PRs closed on GitHub, past quarter (-30% change) * 9 issues opened on GitHub, past quarter (350% increase) * 3 issues closed on GitHub, past quarter (300% increase)

The Committer-to-PMC ratio is roughly 2:1. Community changes, past quarter: - No new PMC members. Last addition was Bohdan Kazydub on 2020-01-28. - No new committers. Last addition was Cong Luo on 2021-01-19. ## Project Activity: The Drill community is gearing up for the release of Drill 1.19 which will be a a very large improvement over Drill 1.18. We project a release date of mid June. Drill 1.19 will include: * New connectors for Cassandra/Scylla and ElasticSearch * Streaming REST API * Improvements to the Kafka, Kudu, and Mongo connectors * Updates to the parquet reader * A format reader for XML data, as well as integration with the REST plugin * Integration of a streaming Excel reader so Drill can read Excel files of arbitrary size * Security improvements to incorporate a password vault * Access controls around storage plugins * Resolution of numerous CVEs * Much more... The Drill community has been requesting more frequent (but smaller) releases, so after Drill 1.19 is released, we will make every effort to move to quarterly releases rather than biannual releases. Recent releases: * 1.18.0 was released on 2020-09-04. * 1.17.0 was released on 2019-12-26. * 1.16.0 was released on 2019-05-02. ## Community Health: The Drill community is healthy with actiivty comparable to last quarter. One metric not reflected here, is that our Slack channel has grown considerably over the last quarter. More dev and user interaction is happening there than via the email lists. Slack doesn't seem to have quarterly metrics, but I will attempt to gather some metrics for the next report. * dev@drill.apache.org had a 21% increase in traffic in the past quarter (622 emails compared to 514) * user@drill.apache.org had a 295% increase in traffic in the past quarter (83 emails compared to 21) * 62 issues opened in JIRA, past quarter (14% increase) * 44 issues closed in JIRA, past quarter (-18% change) * 78 commits in the past quarter (-16% change) * 17 code contributors in the past quarter (13% increase) * 48 PRs opened on GitHub, past quarter (-20% change) * 52 PRs closed on GitHub, past quarter (-8% change)

Since the main developers are based in the US on both coasts, and in Ukraine, we held them at 10AM ET which is 7AM PT, and 1600 CET (Ukraine). The hangout was in English as everyone in the community does speak English. We didn't take minutes, but there were some follow on discussions over email and one concrete result was that Drill's error messages have been significantly improved. ## Community Health: dev@drill.apache.org had a 24% increase in traffic user@drill.apache.org had a 60% increase in traffic 158 issues opened in JIRA (15% increase) 117 issues closed in JIRA (17% increase) 106 commits in the past quarter (6% increase) 13 code contributors (-18% decrease) 102 PRs opened on GitHub (27% increase) 107 PRs closed on GitHub (42% increase)

## Description:
A distributed SQL MPP for Hadoop and NoSQL
## Issues:
- Not at this time.
## Activity:
- The Drill development community has decided to move back to ~monthly
releases after having a long gap between the 1.1 and 1.2 releases.
- A lot of work is currently focused on continued stabilization of the
codebase as we see larger and more complex user deployments.
- The community released 1.2 in October and is in the process of releasing 1.3.
- Some recent new features like access to JDBC sources have drawn in new users.
- The community is working on a new ValueVector initiative that will broaden
collaboration on a piece of the Drill codebase. This should help increase
cross-pollination between the Drill community and other Apache projects.
- Some recent committers have shown great Apache mentality so it seems likely
we will add new PMC members shortly. (something that we haven't done since
we graduated)
- The community is actively voting on adding a couple new committers whose
primary contributions are doc and social media related rather than code
development.
- We've added two new committers in the last quarter.
## Health report:
- The community members get along well and are productive.
- We continue to see nice growth in the user community.
- New developer contributions have been less frequent that we would like to
see.
- Some new developers have found it hard to get started. As such, we continue
to try to make efforts to ease the effort required around becoming a casual
contributor. This includes:
- trying to speed up the unit test suite
- reducing the memory requirements for the unit test suite
- switching to a pull request contribution model as opposed to a
reviewboard/patch model
- improving developer documentation
- exploring options for how to ease effort executing the extended test suite
- marking Newbie tasks on JIRA
## PMC changes:

## Description:
A distributed SQL MPP for Hadoop and NoSQL
## Activity:
- Drill adoption has seen strong increases in the last few months. This is
expected as Drill is now something useful to end users (as opposed to being
mostly in development).
- There have been a number of community events that have been helpful in
continuing to drive adoption and awareness of the project. This includes
countless meetups, talks and tutorials at a number of major conferences (such
as NoSQL Now & Strata/Hadoop World NYC).
- The community has been primarily focused on addressing user issues for the
last few months. Activity continues to increase on the user list post the
1.0 release of Drill.
- Code contributors are starting to appear more frequently. These new
contributions are most often focused on extending Drill (such as storage
plugins, format plugins and udfs)
- A key corporate contributor has created a new extended test suite for
Drill. This will likely be considered for incorporation into the Drill
codebase to provide additional support for product quality goals.
## Health report:
- Drill's community diversity is increasing as we see a broadening of
companies sponsoring engineers to work on Drill. This is due to both new
contributors and existing contributors moving to new companies.
- New contributors are arriving but we need to continue to ease their
experience.
- New contributors currently struggle with a lack of code documentation.
The community is working on improving this to ease the newbie experience.
- New (and existing) contributors find Drill's precommit testing
requirement to be burdensome as the tests typically take 30-40 minutes to
complete. As such the community is looking at ways to speed this up.

Description: Apache Drill is a distributed query layer that supports querying JSON, NoSQL and Hadoop using SQL. Current Activity: Drill continues to see positive energy and discussion on the mailing lists. One of the great things we are now seeing is a broader set of users answering new user queries on the mailing list. This is a positive sign towards further diversification and health of the community.

Description:
Apache Drill is a distributed system for interactive analysis of
large-scale datasets that is based on Google's Dremel. Its goal is to
efficiently process nested data, scale to 10,000 servers or more and to be
able to process petabyes of data and trillions of records in seconds.
Drill has been incubating since 2012-08-11.
In the previous reports, the following were listed as goals before
graduation
1. Complete the feature set
2. Continue to attract new developers/contributors with a variety of
skills and viewpoints
3. Continue the outreach activities to build the early user community for
the technology
These have been achieved and the podling has made several releases with no
more than minor issues that were related to changing requirements for
notices in incubator projects. The next release (0.5) is currently being
voted on. Subsequent to that, the podling is likely to vote to request the
board to graduate Drill to TLP status.

Shepherd notes:
Matt Franklin (mfranklin):
I have reviewed the community and have concluded that it is very active and
healthy. IMO, #3 in the issues to address before graduation is not critical
and can be successfully mitigated by documenting the tasks that are currently
being executed by single individuals. My recommendation is that the Drill
podling begin the graduation process after completion of the next release.
Marvin Humphrey (marvin):
The report is admirably thorough and must have taken a long time to
prepare. Perhaps consider that a report with a reduced level of detail
similar to the other reports may be more in line with Board
expectations.
The report was filed too late to be incorporated into a review by the
assigned shepherd. Please file on time.
Please wrap future reports at 77 columns, and please take more care with
making indentation reflect logical hierarchy. Also, use only
s.apache.org URL shorteners in future reports. Otherwise, someone
downstream must clean up the report -- either someone from the IPMC (I
took care of reformatting this month) or the Board -- before it is
published in the official Board minutes.

Description: Apache Drill is a distributed system for interactive analysis of large-scale datasets that is based on Google's Dremel. Its goal is to efficiently process nested data, scale to 10,000 servers or more and to be able to process petabyes of data and trillions of records in seconds. Drill has been incubating since 2012-08-11. Three Issues to Address in Move to Graduation: 1. Continue to attract new developers with a variety of skills and viewpoints 2. Develop community skills and knowledge by building some releases 3. Demonstrate community robustness by rotating project tasks among multiple project members Issues to Call to Attention of PMC or ASF Board: none How community has developed since last report: Mailing list discussions: There has been active participation in discussions on the developer mailing list, including new participants and developers. A few have participated in the users list; mainly activity takes place on developer mailing list. Activity summary: http://mail-archives.apache.org/mod_mbox/incubator-drill-dev/ June to date 5 June, 29 (mainly jira; some discussion) May 2013, 135 (jira, focused discussions) April 2013, 188 (jira; focused discussions) March 2013 260 (jira, focused discussions) Topics in discussion on the dev mailing list included but not limited to: * Evolution of logical plan syntax with addition of operators including the Value and Union Distinct operators * Advantages and disadvantages of Parquet versus ORC * ValueVector construct and requirements * The relative performance of Janino based compilation versus javax.tools.Javacompiler * Initial development of execution engine environment * Discussion of various types of large array and off heap data structure libraries * RPC protocol and framework Code For details of code commits, see http://bit.ly/14YPXN9 and http://bit.ly/19IyID1 There has been great progress around both evolution of the reference interpreter and In the last three months, there have been many commits including: * Initial implementation of RPC framework * Base client and Zookeeper based client abstraction * SQL parser with JDBC driver * Distributed query scheduling framework * ValueVector implementations * Large number of reference interpreter tests and fixes Community Interactions There is now a weekly Drill hangout conducted remotely through Google hangouts Tuesday mornings 9am Pacific Time to keep core developers in contact in realtime despite geographical separation. Results from these discussions are shared with the discussion list through meeting minutes and all are welcome to attend. This has been helpful in speeding development and averages attendance of 8-10 developers each week. Presentations There have been presentations from community members at conferences, meet-ups and through the weekly Google hangout. * As you can see from http://drill-user.org/ there were few more HUGs/BUGs where Drill was presented/discussed (in Europe) - the blog itself might also be considered to manifest a contribution (?) * We have published an article on Drill in the Big Data journal http://www.liebertpub.com/big Sample presentations: * Introduction to Apache Drill, Bay Area Analytics Group 2 April 2013 by Tomer Shiran * Interactive Ad hoc query at scale: talk at Hadoop User Group UK by @mhausenblas * Apache Drill Technical Overview: talk at Google Hangout, May 22 by Jacques Nadeau available at http://slidesha.re/123mSDh * Drill Technical update @April 16 Hangout by Jacques Nadeau available at http://slidesha.re/ZDBvWP * Drill Dissection at NoSQL matters (April) @mhausenblas video available at http://bit.ly/13Ffk7b * All You Need to Know About Drill, talk during Big Data Week #bdw13 by Michael Hausenblas on 26 April http://bit.ly/17L1rD * Deep Dive into Drill Implementation 3 June at Berlin Buzzwords by Ted Dunning and Michael Hausenblas Slides Slides from Drill presentations posted online such as at slideshare get a large number and increasing number of views.

Mailing lists are seeing a ton of traffic and work in the sandbox seems to be progressing at a reasonable pace. Question to the community: When do you estimate that you would want to start putting a preliminary release of some kind together? I assume this would require identifying at least some components that should be moved from "sandbox".
Project Summary: Drill is a distributed system for interactive analysis of large-scale datasets, inspired by Google's Dremel. Drill has been incubating since 2012-08-11. Issues: Discussions on these key areas were __very focused__ and productive toward this project's graduation goals: Healthy discussion of target use cases from the community New Syntax Interpreter Continued Logical Plan Syntax discussion & development (with focus on JSON) Leveraging existing ideas/lessons learned from Optiq, LucidDB, DynamoBI, Eigenbase and Saffron How has the community & project developed since the last report: User interest has slowed due to the Holiday season but discussion on the the above topics is healthy. Commit and list activity are consistent with the above. Development is continuing onward. An addition of employer supported contributor to the project. New users continue to ask to be formally part of this project. On going discussion with schema-less data scanners amongst the project members. There is some cause for concern due to a drift toward isolated development of components with less on-list discussion than before. We will work to encourage more public styles of work.

Issues: Discussions on these key areas were __very focused__ and productive toward this project's graduation goals: 1.) Logical Plan Expressions, syntax, and parser 2.) Schema-less Management 3.) Wire Protocols User interest has increased (thanks to the media) and as the project's source commitments increase so will user interaction within the next quarter. How has the community developed since the last report: Discussion counts have gotten smaller from the month of October through November 2012. For all intents and purposes initial code was checked in and builds running during the middle of October 2012 and from that time focused discussion and development have occurred. Many new users joined the list as well as asking formally to be part of the community. List Summary: * http://mail-archives.apache.org/mod_mbox/incubator-drill-dev/ * Dec 2012, [current], 264 subscribers * Nov 2012, 73 (jira, focused discussions) * Oct 2012, 214 (svn, discussions, jira) * Sep 2012, 413 * Aug 2012, 85 How has the project developed since the last report: == Milestones == 1.) During the month of October, the SVN repository was initiated and initial source checked in. 2.) ~88% of JIRA tasks were created during the months October through November, showing growth and healthy discussion. 3.) Post initial commit, many users have come forth asking to engage in active development, showing healthy growth and interest amongst the developer community at large regarding the goals of this project.

Drill's goal is to build an open source clone of Dremel with appropriate extensions to foster greater flexibility. Drill has been incubating since September of 2012. Since last month, we have been working on bringing in existing code assets. We now have the following items in our source repository: - A web-based GUI front-end for DRILL - A query parser for a Dremel equivalent language - An early prototype of a physical plan interpreter The web front-end and query parser still need formalized IP clearance including ICLA's or CCLA's as appropriate. Informal clearances have been granted on all components. In terms of infrastructure, the project web site has been incorporated into CMS. Graduation is still very far away, but the community activity has been high and the mailing list has been active with over 200 postings in October. Numerous public presentations have been made since the last report. Most important issues to address before we can graduate: Get the basics in place, build up a working code base, make releases (that is, everything) Any issues the Incubator PMC or ASF board need to be aware of: None at this time How has the community developed since the last report: The active contributors mentioned in the previous report continue to be active and additional contributors have been identified. At least one corporate supporter of the project has hired a full-time engineer to focus on Drill. We are working to bind these new contributors into the community and several appear likely to become committers over time. How has the project developed since the last report: The community has continued to make progress and substantial code assets are in the process of being contributed. Signed-off-by: berndf
Drill's goal is to build an open source clone of Dremel with appropriate extensions to foster greater flexibility. Drill has been incubating since September of 2012. Since last month, we have been working on infrastructure. A prototype web-site is ready and several code contributions are nearly ready to commit. Graduation is still very far away, but the community activity has been high and the mailing list has been active. Numerous public presentations have been made and several Drill Users' Groups have been formed and meetings held. Most important issues to address before we can graduate: Get the basics in place, build up a working code base, make releases (that is, everything) Any issues the Incubator PMC or ASF board need to be aware of: None at this time How has the community developed since the last report: Several active contributors outside the current committer group have emerged. We are working to bind these new contributors into the community and several appear likely to become committers over time. How has the project developed since the last report: The community has begun to gel nicely and significant code contributions have moved forward. Signed-off-by: Ted Dunning acting for Grant Ingersoll
Drill is a distributed system for interactive analysis of large-scale datasets, inspired by Google's Dremel. We have just started and have mailing lists and svn up. Git has been delayed by issues in infra. Community development is progressing well with several companies offering paid developers and 90 subscribers to the dev list. A hackathon in the SF bay area is scheduled. A lunchtime meetup is scheduled for Boston. Additional meetups in New York and London are in the planning stages. All such physical meetups will have remote access if possible (probably not for the lunch) and all will be reported back to the mailing list to be sure to include those in different places and time zones can participate. Graduation is still a distant vision since we haven't got all the basic mechanics in place yet. The community side of things is going well and the development of a realistic release looks like it will be moving shortly. Signed-off-by: tdunning
