| <p>The <a href="">Apache Calcite PMC</a> |
| is pleased to announce |
| <a href="/docs/history.html#v1-9-0">Apache Calcite release 1.9.0</a>.</p> |
| |
| <p>This release includes extensions and fixes for the Druid adapter. New features were |
| added, such as the capability to |
| <a href="https://issues.apache.org/jira/browse/CALCITE-1357">recognize and translate Timeseries and TopN Druid queries</a>. |
| Moreover, this release contains multiple bug fixes over the initial implementation of the |
| adapter. It is worth mentioning that most of these fixes were contributed by Druid developers, |
| which demonstrates the good reception of the adapter by that community.</p> |
| |
| <p>We have added new SQL features too, e.g., |
| <a href="https://issues.apache.org/jira/browse/CALCITE-1309">support for <code class="highlighter-rouge">LATERAL TABLE</code></a>. |
| There are multiple interesting extensions to the planner rules that should contribute to |
| obtain better plans, such as |
| <a href="https://issues.apache.org/jira/browse/CALCITE-1288">avoiding doing the same join twice</a> |
| in the presence of <code class="highlighter-rouge">COUNT DISTINCT</code>, or being able to |
| <a href="https://issues.apache.org/jira/browse/CALCITE-1220">simplify the expressions</a> |
| in the plan further. In addition, we implemented a rule to |
| <a href="https://issues.apache.org/jira/browse/CALCITE-1334">convert predicates on <code class="highlighter-rouge">EXTRACT</code> function calls into date ranges</a>. |
| The rule is not specific to Druid; however, in principle, it will be useful to identify |
| filter conditions on the time dimension of Druid data sources.</p> |
| |
| <p>Finally, the release includes more than thirty bug-fixes, minor enhancements and internal |
| changes to planner rules and APIs.</p> |
| |
| |
