> Key: IMPALA-10898
> URL: https://issues.apache.org/jira/browse/IMPALA-10898
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Critical
>
> 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.
