Subject Board report

Here is the report I propose to file for the 1/20 Apache board meeting. Comments?



Attachment K: 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.

  As a framework, Calciteā€™s audience is fairly small, consisting
  mainly of developers building data engines (Drill, Phoenix, Hive for
  example) but also streaming engines such as Samza, and some
  commercial engines using Calcite for query planning and its Avatica
  JDBC layer.

## Issues:

 - There are no issues requiring board attention at this time.

## Activity:

 - New alliances with streaming projects:
   - Storm committed initial SQL support based on Calcite;
   - Flink announced plans to use Calcite develop a SQL interface for
     both streaming and traditional queries.
 - Release schedule a bit slow due to the holidays, but 1.6 will
   probably happen mid-January.
 - List, JIRA, and commit activity are about above average.
