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 [1] https://github.com/apache/incubator-calcite/blob/master/doc/HISTORY.md#100-incubating--2015-01-31 [2] http://www.apache.org/dyn/closer.cgi/incubator/calcite [3] http://calcite.incubator.apache.org --- 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. --------------------------------------------------------------------- To unsubscribe, e-mail: general-unsubscr...@incubator.apache.org For additional commands, e-mail: general-h...@incubator.apache.org
