Polaris

19 Mar 2025 ¶

Polaris is a catalog for data lakes. It provides new levels of choice,
flexibility and control over data, with full enterprise security and Apache
Iceberg interoperability across a multitude of engines and infrastructure.

Polaris has been incubating since 2024-08-09.

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

 1. Prepare 1.0.0 release including binary distribution
 2. Grow the community

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

 No

### How has the community developed since the last report?

 Regarding the users community:
 - on Slack (#general channel), in February, we had questions from 11 new
 users, evaluating Polaris. These users are not active on the dev mailing
 list (only Slack).
 - on GitHub Issues, in February, we had 2 new issues created by non
 committers users, and non affiliated to initial committed companies. Some
 users are the same active on Slack (for instance
 https://github.com/apache/polaris/issues/996)

 Regarding the contributors community:
 - in February, we had 7 PRs from 5 new contributors (individual
 contributors, not affiliated to companies already active in Polaris)
 - in February, we had several GitHub issues and PRs created by 3 new
 contributors from Snowflake and a new contributor from Dremio.

 In February, we had several Community Meetings (recorded and shared on
 the dev mailing list and website):
 - 2 Polaris Community Meetings
 - Discussion about the Policy Management proposal
 - Discussion about Polaris Persistence improvement proposal

 On these meetings, we were pleased to see several new people (around 15
 people show up for the first time in February).

 We continue to promote Polaris in order to grow our community. We
 strongly believe 1.0.0 release (with the binary distributions) will help to
 grow even faster our community.

### How has the project developed since the last report?

 0.9.0 has been released. This release is the first one on the project,
 only including source distribution.
 We are now working on 1.0.0 release that will include binary
 distributions.

 We published a roadmap proposal
 (https://github.com/apache/polaris/discussions/1028), and we added a
 1.0-blocker label on GH Issues.

 In February, we had 3 new proposals in discussion (relayed on the dev
 mailing list):
 - Persistence layer improvement (https://github.com/apache/polaris/issues/985)
 - Policy Management (https://github.com/apache/polaris/issues/999)
 - Generic Table Support (https://github.com/apache/polaris/issues/1048)

 We are now focusing on 1.0.0 preparation, including fixes and the
 persistence layer improvement.

 release, including binary distributions.

### Are there any issues that the IPMC or ASF Board need to be aware of?
 No

### How has the community developed since the last report?

 - All discussions (design proposals, process improvements) are discussed
on
 the mailing list (94 messages on the dev mailing in Dec 24, 196 in Jan 25
 for instance)
 - New users showed on Slack:
 - New contributors interested to work on key features for Polaris (2
 expressed interest for storage backend and TMS)
 - Two new committers have been elected during the last quarter (Dmitri

    Comments:  Fixed some formatting in the report. For community
    development, are there more specific data points (other than "more")?
How
    many contributions are coming from contributors outside of the
original set
    of contributors and companies? In these reports, try to focus more on
    community growth and development than project development.

    Comments:  I'm glad to see the list of new committers! That's great
    news given how long the project has been active, but it indicates
    that perhaps there's something to report in the report section "How
    has the project developed since the last report"? Perhaps that's
    an oversight.
