IMPALA-13457: Calcite planner: fix datetime/interval issues for tpcds queries
Added support for datetime interval operators. A dummy IntervalExpr
was added to support logical to physical representation. The
IntervalExpr is removed once the actual "+" operation for datetime
is created, but the translation framework is simplified by working
on the Calcite interval type in a separate temporary Expr.
Some logic was inserted into CoerceOperandShuttle. This object is
used to add casts when there is limitation in Calcite for number types.
When we have an interval, we always want to represent it as a special
type so we do not want to introduce a cast.
Also, in ImpalaOperatorTable, the ability to use Impala functions over
Calcite functions are needed because Calcite translates the year function
into "extract" which causes some issues. Just using the Impala signature
works for us here.
