| |
| <p>On October 21st, 2015 the board of the |
| <a href="https://www.apache.org">Apache Software Foundation</a> |
| voted to establish Calcite as a top-level Apache project.</p> |
| |
| <p><img src="/img/cake.jpg" alt="Calcite's graduation cake" /></p> |
| |
| <p>Describing itself as “the foundation for your next high-performance |
| database”, Calcite is a |
| <a href="/docs/">framework for building data management systems</a>. |
| Calcite includes a comprehensive implementation of relational algebra |
| and an extensible cost-based query optimizer. It also includes an |
| optional SQL parser and JDBC driver.</p> |
| |
| <p>Calcite joined Apache as an incubator project in May, 2014. To |
| graduate from the incubator, projects have to prove that they can |
| create high quality releases, form a diverse community, and operate as |
| a meritocracy.</p> |
| |
| <p>Calcite’s committers have delivered eight releases during incubation |
| (roughly one every two months) including the |
| <a href="/news/2015/01/31/release-1.0.0-incubating/">milestone 1.0 release in January, 2015</a>.</p> |
| |
| <p>The project has become a key component in many high-performance |
| databases, including the |
| <a href="https://drill.apache.org">Apache Drill</a>, |
| <a href="https://hive.apache.org">Apache Hive</a>, |
| <a href="https://kylin.apache.org">Apache Kylin</a> and |
| <a href="https://phoenix.apache.org">Apache Phoenix</a> open source projects, |
| and several commercial products.</p> |
| |
| <p>Also, in collaboration with <a href="https://samza.apache.org">Apache Samza</a> and |
| <a href="https://storm.apache.org">Apache Storm</a>, Calcite is developing |
| <a href="/docs/stream.html">streaming extensions to standard SQL</a>.</p> |
| |
| <p>The Calcite community met at a hangout on October 27th, 2015, and |
| celebrated with a graduation cake.</p> |
