Dylan Guedes commented on SPARK-28500:
--------------------------------------

Hmm you are correct, there's some overlapping there. However, at some point the JIRA will
be fragmented into smaller ones, like one for filter, other for distinct, right?

> Definition: "The {{filter}} clause extends aggregate functions ({{sum}}, {{avg}}, {{count}},
…) by an additional {{where}} clause. The result of the aggregate is built from only the
rows that satisfy the additional {{where}} clause too." [source|[https://modern-sql.com/feature/filter]]
> Also, PgSQL currently support `filter` while Spark doesn't.
