Attachment ZZZ: Report from the Apache Calcite Project [Julian Hyde]
## Description
Apache Calcite is a highly customizable engine for parsing and
planning queries on data in a wide variety of formats. It allows
database-like access, and in particular a SQL interface and advanced
query optimization, for data not residing in a traditional database.
Calcite graduated from the Apache Incubator on October 21, 2015.
Avatica is a sub-module within Calcite, and provides a framework for
building local and remote JDBC and ODBC database drivers. Since March
2016, Avatica has an independent release schedule.
## Issues:
- There are no issues requiring board attention at this time.
## Activity:
- Avatica split
Avatica became an independently released module. Previously the 4
Avatica artifacts were released as part of Calcite, but now releases
and release numbers are decoupled from Calcite releases. Avatica has
its own section of the web site, http://calcite.apache.org/avatica/.
Our motivation is that other projects (e.g. Apache Phoenix's Query
Server) depend only on Avatica, and are likely to require
maintenance releases. Also, Avatica does not depend on Calcite, and
the perception that it has few dependencies will improve adoption.
Avatica is still governed by the Calcite PMC, and developed using
the same git repo and dev list. Communities are diverging slightly,
but there is still significant overlap.
- A new adapter for Apache Cassandra
- Talks
* Julian Hyde spoke about Streaming SQL & Calcite at an Apache Samza
meetup (Mountain View) on Feb 17.
* Julian Hyde and James Taylor presented a Developer Showcase at
Strata conference (San Jose) on Mar 30.
* Upcoming talks at ApacheCon BigData (Vancouver), Hadoop Summit
(Dublin), Kafka Summit (San Francisco), XLDB (Palo Alto),
Hortonworks User Group (Herndon, VA).
## Health report:
- Mailing lists are a little above typical levels (585 emails on dev)
- JIRA at typical levels (141 created, 116 closed)
- The community wants to try to keep the volume on the dev list at
reasonable levels. During this quarter, we decided to post each
created JIRA case to the dev list in the hope that this would drive
discussions from dev onto JIRA cases, and thereby reduce dev volume.
