## Board comment in the last report:
rb : A reprise of a comment from an earlier month: You refer to active
contributors from 30+ organizations, and 130 contributors, but you then
mention only 19 committers. Who are these contributors, and are you actively
considering which of them may become committers? Don't make the mistake of
setting the bar so high that these contributors go away feeling that they have
not received the recognition that they've earned!
reply : Thanks for the kind reminder. Sure, we will actively identify the
active contributors to become committers. Last month,the CarbonData community
had 1 new committer and 1 new PMC.
## Issues:
- There are no new issues requiring board attention at this time.
## Activity:
- Community is pretty active, contributors who are from many different
organizations , and now the number of contributors is more than 140+, we are
receiving around 200 pull requests per month.
- We are focus on the two releases(1.5.1 and 1.5.2) in the last 3 months,
which provided many significant features, such as : integration with spark
2.3.2 and hadoop 3.1.1, improve scan performance, support modify column name
after table created, support C++ Interfaces with multi-threads to Query
Data from CarbonData, further optimize complex data type, support gzip
compressor to get better compression ratio etc.
- The community helped many users to test carbondata and deploy carbondata in
production via mailing list.

Apache CarbonData is a new Apache Hadoop native file format for faster interactive query using advanced columnar storage, index, compression and encoding techniques to improve computing efficiency, in turn it will help speedup queries an order of magnitude faster over PetaBytes of data. CarbonData has been incubating since 2016-06-02. Three most important issues to address in the move towards graduation: 1. Prepare a couple of new releases 2. Increase the communities 3. Prepare website 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? The community activity increased: many new users started to use and test CarbonData, we had more than 300 issues created till Nov; Two new finance enterprises have formally deployed CarbonData to their business system,and the query performance speeded up 10-70 times in comparison to old system (both are bank enterprise in China). We finished 2nd Meetup in Beijing on 29th Oct, and CarbonData has increased 10+ contributors in last month. How has the project developed since the last report? Code donation has been done and all resources have been created by INFRA(git, github mirror, mailing list, Jira, ...). We also created the Jenkins CI jobs, and preparing org website. We did the 2nd release (0.1.1-incubating) in Oct and we are preparing a new one(0.2.0) in Nov. We have finished 2 technical talks in Bay area with Databricks, Alluxio in last month for discussing ecosystem integration with Spark and Alluxio. Date of last release: 2016-10-10 When were the last committers or PMC members elected? We elected a new committer Kumar Vishal on 2016-10-15.

The community activity increased: many new users started to use and test CarbonData, we had more than 100 new issues created during Aug; One user formally deployed CarbonData to their business system, the query efficiency speeded up 50 times (the user is the biggest internet finance company in China) How has the project developed since the last report? Code donation has been done and all resources have been created by INFRA (git, github mirror, mailing list, Jira, ...). We also created the Jenkins CI jobs. We did the first release (0.1.0-incubating) and we are preparing a new one. We're also working on the website (with improved look'n feel).
