---------------------------------------
Summary: Multiple min-max filters per column
Key: IMPALA-8084
URL: https://issues.apache.org/jira/browse/IMPALA-8084
Project: IMPALA
Issue Type: Improvement
Reporter: Janaki Lahorani
It looks like we are sending one min-max filter per column to Kudu. But the
potential to filter more data can be realized by sending multiple ranges. It
will be beneficial to evaluate whether Kudu can accept multiple min-max
filters. If needed, enhance Kudu to accept multiple ranges per column. The
filter count is inversely proportional to density: denser data set needs less
number of filters.
