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. + +We have added new SQL features too, e.g., +<a href="https://issues.apache.org/jira/browse/CALCITE-1309";>support for `LATERAL TABLE`</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 `COUNT DISTINCT`, 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 `EXTRACT` 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. + +Finally, the release includes more than thirty bug-fixes, minor enhancements and internal +changes to planner rules and APIs.
