> Currently used H2 based query execution engine has a number of critical
> limitations Which do not allow to execute an arbitrary query.
> The ticket aims to show potential of a new, Calcite based, execution engine
> which may act not worse than current one on co-located queries, provide a
> boost for queries, using distributed joins, and provide an ability to execute
> arbitrary queries, requiring more than one map-reduce step in execution flow.
