[DISCUSS] March board report

[Ryan Blue <bl...@apache.org>]

Hi everyone,

It’s already time for us to report project status to the ASF board. Sorry
that I’m a couple of days late!

Here’s what I just submitted. Feel free to reply with updates if you want
anything added!

Description:

Apache Iceberg is a table format for huge analytic datasets that is designed
for high performance and ease of use.
Issues:

There are no issues requiring board attention.
Membership Data:

Apache Iceberg was founded 2020-05-19 (2 years ago)
There are currently 19 committers and 12 PMC members in this project.
The Committer-to-PMC ratio is roughly 5:3.

Community changes, past quarter:

   - No new PMC members. Last addition was Jack Ye on 2021-11-14.
   - Szehon Ho was added as committer on 2022-03-07

Project Activity:

Iceberg 0.13.0 was released on 2022-02-01, and was followed quickly by
0.13.1 on
2022-02-14 to fix a performance regression.

The 0.13 release included many significant new features:

   - Spark 3.2 support and overhauled row-level plans
   - Flink 1.13 and 1.14 support
   - Spark and Flink modules built and tested against each engine version
   - GCS and Aliyun OSS IO integration

The community has also been working on some major features:

   - Delta-based MERGE INTO and UPDATE plans for Spark (complete)
   - Scala 2.13 support for Spark 3.2 (complete)
   - IO metrics collection (complete)
   - Vectorized reads with delete files (complete)
   - An implementation of table branching and tagging
   - Addition of a REST catalog spec, like the Hive Thrift interface for
   Iceberg
   - Addition of a view spec that tracks SQL or other plan representations
   - Spec updates for secondary indexes and metrics
   - Spec updates for default values

In addition to features, the community also overhauled the ASF site. The new
site better communicates Iceberg’s major features and has version-specific
docs.

There were 6 Iceberg talks at the Subsurface conference and the conference
organizers noted it was a major theme. On the last report, we were asked
whether
the presentations are available on the Iceberg site. They are present under
the
Talks tab.
Community Health:

Community health continues to be good. There were some decreases this
quarter in
metrics like dev list traffic and issues opened, but this isn’t concerning
with
the context of the last few quarters of growth and that this report includes
December when many people are on holiday. In addition, the number of unique
contributors increased to 81 (20% higher).
