Julian Hyde commented on CALCITE-1655:
--------------------------------------
[~bslim], I don't think you should use Mockito. RexNode is quite
straightforward to instantiate: see RexBuilderTest and RexProgramTest for
examples. Using the real thing will make the tests easier to read, maintain and
extend.
I think you should add tests for some other types, such as timestamp and
decimal.
> Add In filter to druid adapter.

> Project: Calcite
> Issue Type: Bug
> Components: druid
> Reporter: slim bouguerra
> Assignee: Julian Hyde
>
> The druid calcite adapter throw an exception when an IN filter is used.
> This happens only in hive because in calcite project the IN filter is
> transformed to OR automatically.
> Since this rule does not kick in HIVE and it is better to use the native IN
> filter from druid instead having huge number of OR clauses i will send a
> patch that adds the IN filter.
