Impala August 2020 board report
Here is the report I pushed just now. Corrections welcome!
## Description:
The mission of Apache Impala is the creation and maintenance of software
related to a high-performance distributed SQL engine
## Issues:
There are no issues requiring board attention.
## Membership Data:
Apache Impala was founded 2017-11-14 (3 years ago)
There are currently 52 committers and 33 PMC members in this project.
The Committer-to-PMC ratio is roughly 7:5.
Community changes, past quarter:
- No new PMC members. Last addition was Csaba Ringhofer on 2020-02-18.
- Anurag Mantripragada was added as committer on 2020-05-13
## Project Activity:
This quarter, the Impala community added support (or improved support) for:
- GROUPING, INTERSECT DISTINCT, EXCEPT DISTINCT, and uncorrelated
subqueries
in HAVING
- Development environment bootstrapping with GCC 7 and on Ubuntu 20.04 and
SLES12 sp5
- Sanitizers like ASAN and TSAN in developer testing
- Asynchronous code execution so a query can start in interpreted mode and
switch to native code when code generation is complete
- TPCDS queries in the test suite
- Running in containerized environments
The Impala community improved compatibility with other Apache projects by:
- Adopting Apache DataSketches KLL structure for quantile estimation
- Recognizing the new ASF URL practices when downloading Maven and Ant
- Improving support for Apache Hive ACID tables
- Adding Apache Iceberg CREATE TABLE support
- Adding a number of Apache Kudu compatibility improvements
- Supporting Apache Parquet FIXED_LEN_BYTE_ARRAY DECIMAL
- Supporting Apache Hadoop Ozone in "load data inpath"
The Impala community removed some or all support for the following in the
4.0
branch:
- Dateless timestamps
- Impala-lzo
- Sentry
- Hive 2
## Community Health:
The community is overall healthy. This quarter has a common amount of
variability in some previous metrics. It is not infrequent that this
variability has no plainly obvious cause.
- Commits are down this quarter from 221 to 197.
- Six community members authored their first patch.
- JIRAs created is down to 315 from 360; JIRAs resolved are up
to 357 from 243. A significant number of these are Later, WontFix,
CannotReproduce, etc.
- user@ traffic is up 50% to 30 emails; dev@ traffic is down 48% to 69
emails.
