[ANNOUNCE] Apache Calcite 0.9.2 (incubating) released

[Julian Hyde <jh...@apache.org>]

I am pleased to announce Apache Calcite release 0.9.2 (incubating).

Apache Calcite is a dynamic data management framework. You can use Calcite
as a toolkit for building a SQL:2011 compliant parser, validator and query
planner for your database; several well-known projects including Apache
Hive and Apache Drill do this. Calcite can also mediate between a JDBC
application and one or more relational or non-relational data sources,
executing the parts of the query that cannot be pushed down to the data
source, and using materialized query
results to improve query performance.

It is a fairly minor release, and last release before we rename all of the
packages and lots of classes, in what we expect to call 1.0. It will be
a useful stepping stone for people upgrading. However, there are a number
of bug fixes and improvements, including an SPI that makes it easier to
implement your own tables, pushing down projections and filters. Read about
other bug fixes and improvements in the release notes [1].

The release is available to download via the “Releases” menu of the home
page [2].

Julian
