Attachment O: Report from the Apache Calcite Project [Jesús Camacho Rodríguez]
## Description:
Apache Calcite is a highly customizable framework 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.
Avatica is a sub-module within Calcite, and provides a framework
for building local and remote JDBC and ODBC database drivers. Avatica
has an independent release schedule, and since April 2017, it has its
own independent repository.
## Issues:
- There are no issues requiring board attention at this time.
## Activity:
Development and mailing list activity is steady for both Calcite and
its Avatica sub-project.
Since the last board meeting, there has been one Calcite release
and one Avatica release.
Avatica 1.10.0 was released at the end of May. As the Calcite and
Avatica projects become more separate, this was the first release
since Avatica’s git repository separated from Calcite’s repository
during the previous quarter. The release added support for JDBC Array
data, Docker, and JDK 9 (it continues to run on JDK 7 and 8).
In total, there were over 20 new features and bug fixes.
In turn, Calcite 1.13.0 was released at the end of June. The release
included more than 75 resolved issues, comprising a large number of
new features as well as general improvements and bug-fixes. Among
others, Calcite was upgraded to use the recently released version of
Avatica.
Our community continued growing this quarter: three new committers
(Slim Bouguerra, Kevin Liew, and Zhiqiang He) were added to the project.
Finally, there was an important presence of the Apache Calcite project
in talks at multiple events, such as Apache: Big Data North America 2017
(Miami, FL), PhoenixCon (San Francisco, CA) and
DataWorks Summit USA 2017 (San Jose, CA).
