> 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.
