>
> Currently Impala has two kinds of runtime filters: bloom filter and min-max
> filter. Unfortunately they can't leverage the bloom filters in ORC files.
> Only EQUALS and IN-list
> predicates can leverage them to skip unrelated ORC RowGroups.
> This JIRA aims to add runtime IN-list filters for small build side (e.g.
> #rows <= 1024) of a hash join.
