Jesus Camacho Rodriguez commented on HIVE-12968:
------------------------------------------------
I think even if the original case for this patch is covered in Calcite, it
would be still useful for readability of predicates in plans.
E.g.
{noformat}
predicate: (((date is not null and dealid is not null) and cityid is not null)
and userid is not null) (type: boolean)
{noformat}
becomes:
{noformat}
predicate: (date is not null and dealid is not null and cityid is not null and
userid is not null) (type: boolean)
{noformat}
> genNotNullFilterForJoinSourcePlan: needs to merge predicates into the
> multi-AND

> predicate: ((cbigint is not null and cint is not null) and cint BETWEEN
> 1000000 AND 3000000) (type: boolean)
> {code}
> does not fold the IS_NULL on cint, because of the structure of the AND clause.
