----------------------------------
Summary: To take advantage of pre-aggregate results when
generating plans for aggregation
Key: DRILL-6077
URL: https://issues.apache.org/jira/browse/DRILL-6077
Project: Apache Drill
Issue Type: Bug
Reporter: Chunhui Shi
User could generate aggregation results (count, avg, min, max) for segments of
data stored either in summary tables or in metadata stores. Planner should be
able to leverage these results either by direct querying these pre-aggregation
results from these summary tables or combining pre-aggregation results of old
data with results from new data.
