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
* 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].

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.
