The following is the board report I just posted. Comments welcome; the
report can still be edited before the board meeting on the 21st.
## Description:
Apache Impala is a high-performance distributed SQL engine.
## Issues:
There are no issues requiring board attention.

The Committer-to-PMC ratio is roughly 7:4.

## Project Activity:
Notable activity in the last quarter includes:
- Numerous commits related to support for Hive's ACID table format
- Improvements to the consideration of nodes as individual executors
or coordinators, including:
- Improvements to admission control and executor pool management when
there is a dedicated coordinator
- "Executor groups", a feature that allows users to run different
queries in disjoint sets of executors
- The addition of admission control parameters that scale with
the number of executors
- Improvements the developer experience on Docker
- Increased compatibility with Apache projects, including Hive 3,
erasure coding and S3Guard in HDFS, page skipping and Zstd and lz4
compression in Parquet, and miscellaneous compatibility improvements
for Ranger, Knox, Kudu, and Atlas
- The addition of several built-in functions for the DATE type as
well as the ability to read and write DATE in Parquet
- Move closer to deprecating the Beeswax protocol by adding HS2
support to the Impala shell
- Numerous patches improving tracing, logging, and metrics
- Multiple improvements to build times or isolation
- The addition of a data cache for remote reads, improving TPC-DS
performance on S3 by 30% in one scenario, which made S3 performance
as good as HDFS-on-EBS
## Community Health:
By almost all metrics, Impala activity is down quarter-over-quarter
and year-over-year. That said, the project is still very active, with
each day featuring approximately:
- Three commits
- Two dev@ emails
- 25 JIRA updates
- 70 code reviews or patch updates
