Julian Hyde commented on CALCITE-1235:
--------------------------------------
It's a bit surprising to see a rule depend on {{EnumerableLimit}}, because it
is a physical operator. I know there is no logical "pure" limit, only Sort,
which may contain a limit. I suspect you could still find the right plan if you
operated on a logical sort, pushing down the limit only if the sort key is
empty.
I saw that you have a predicate that always returns true. You can use
{{Predicates.<CassandraSort>alwaysTrue()}}.
> Push down LIMIT in unfiltered Cassandra queries
