                 URL: https://issues.apache.org/jira/browse/KUDU-3140
             Project: Kudu
          Issue Type: Improvement

    Affects Versions: 1.12.0
            Reporter: Bankim Bhavsar

KUDU-2483 introduced support for Bloom filter predicate.
However as observed with TPCH, query 9 exhibits regression when Bloom filter predicates are pushed down to kudu.

See excerpt from performance analysis of TPCH run by [~wzhou].
