Subject [ANNOUNCE] Apache Calcite 1.0.0 (incubating) released
Date Mon, 09 Feb 2015 23:38:37 GMT
Hi all,

I am pleased to announce Apache Calcite release 1.0.0 (incubating).

Apache Calcite is a dynamic data management framework.  It
contains the building blocks of a modern database management
system: extensible relational algebra, pluggable metadata,
operators and cost model, cost-based query planner, and optional
SQL:2011-compliant parser, validator and JDBC driver.

Thanks to everyone who has contributed to this release.

This is Calcite's first major release. The release adds:
* SQL support for GROUPING SETS, EXTEND, UPSERT and sequences;
* a remote JDBC driver;
* improvements to the planner engine and built-in planner rules;
* improvements to the algorithms that implement the relational
  algebra, including an interpreter that can evaluate queries without
  compilation;
* about 35 bug fixes.

Since the previous release we have re-organized the code into the
org.apache.calcite namespace; the release notes[1] describe how
to migrate code that used the old APIs.

The release can be obtained from an Apache Mirror[2].

For general information on Apache Calcite, please visit the home
page[3].

Regards,
Julian Hyde, on behalf of Apache Calcite PPMC

Disclaimer

Apache Calcite is an effort undergoing incubation at the Apache
Software Foundation (ASF), sponsored by the Apache Incubator PMC.

Incubation is required of all newly accepted projects until a
further review indicates that the infrastructure, communications,
and decision making process have stabilized in a manner
consistent with other successful ASF projects.

While incubation status is not necessarily a reflection of the
completeness or stability of the code, it does indicate that the
project has yet to be fully endorsed by the ASF.
