Liya Fan updated CALCITE-4342:
------------------------------
Description: As discussed in the mailing list, there are more aggregate
functions (e.g. SINGLE_VALUE, ANY_VALUE) that can be classified as splittable
and ignore distinct optionality. We need to tell the optimizer explicitly about
this, so more optimizations can be applied in various scenarios. (was: As
discussed in the mailing list, there are more aggregate functions (e.g.
SINGLE_VALUE, ANY_VALUE) that can be classified as splittable and
duplicate-insensitive. We need to tell the optimizer explicitly about this, so
more optimizations can be applied in various scenarios. )
