change. Overall, our community health is good.

### Three most important unfinished issues to address before graduating:

 1. Activity on the mailing list. Most of the discussion happens on pinot
 slack channel

 join the mailing list but very few did.

### Are there any issues that the IPMC or ASF Board need to be aware of?

 1. Most Apache projects have slack channels, is there any effort from
 IPMC to formally recognize project slack channel as a first-class citizen.
 2. If there is any interest, the Pinot Podling can volunteer to drive
 this effort.

    Comments:  good progress.. how can we grow more committers? also dev@
    traffic is very light - only 9 threads in the last 3 months.

### IPMC/Shepherd notes:
 Dave Fisher - I see the start of a VOTE for a committer on private@
 There has been no response from other PPMC members. That is disappointing.
 This could be because most of the PPMC members are not subscribed to
 private@. This includes one of the Mentors who signed off on the report.

 Justin Mclean: The items listed under community development seem more
 about project development. How has the community developed?
 I'd also like to see answer to all questions, it make it hard to
 judge process and for us to help if information is not supplied.

  1. Increasing frequency of release
  2. Adding more committers from open source community
  3. Getting word out from community (blogs, etc.)

### Are there any issues that the IPMC or ASF Board need to be aware of?

  Pinot release is scheduled to happen quarterly but has been delayed due
  to a bug we found in helix that was very hard to track down.
  https://github.com/apache/helix/issues/331. We finally
  found the issue, and should be cutting the next release shortly.

### How has the community developed since the last report?
  We have had open-source contributions to integrate Calcite SQL parser,
  support for transforms in selections and filters, support for kafka-2.0,
  and several other bug fixes and performance enhancements. Other
  contributions on upsert feature, and deep-store commit are in the design
  process.
  Contributions from outside of Linkedin:
   - UDF support in filter predicates:
   https://github.com/apache/incubator-pinot/pull/4365
   - Kafka 2.0 support (work authored across open source community):
   https://github.com/apache/incubator-pinot/pull/4397
   - Variable length bytes dictionary support:
   https://github.com/apache/incubator-pinot/pull/4321
   - PQL to SQL enhancement Phase-1 :
   https://github.com/apache/incubator-pinot/pull/4216
   - Ideas and discussions on null value support:
   https://github.com/apache/incubator-pinot/issues/4230
   - Ideas and discussions on SQL support:
   https://github.com/apache/incubator-pinot/issues/4219


### How has the project developed since the last report?
  1. Support for Kafka-2.0 added
  2. Work in progress to move closer to SQL syntax and semantics for
  constructs supported.
  3. Helix and Pinot controller separation in final phase of development.

Pinot is a distributed columnar storage engine that can ingest data in real-
time and serve analytical queries at low latency.

Pinot has been incubating since 2018-10-17.

Three most important unfinished issues to address before graduating:

 1. Building community contribution
 2. Establish a successful release cadence

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

 None

How has the community developed since the last report?

 External contributors have made improvements to real-time segment
 split-commit algorithm to minimize controller access to segment store
 during segment commit phase. In addition they have also contributed
 towards other bug fixes, especially in the real-time area.

How has the project developed since the last report?

 - We made our first release Apache Pinot 0.1.0
 - We have added and improved a lot more documentation
