Summary: Support column histogram statistics
Key: DRILL-6992
URL: https://issues.apache.org/jira/browse/DRILL-6992
Project: Apache Drill
Issue Type: New Feature
Components: Query Planning & Optimization

Reporter: Aman Sinha
Assignee: Aman Sinha
As a follow-up to [DRILL-1328|https://issues.apache.org/jira/browse/DRILL-1328]
which is adding NDV (num distinct values) support and creating the framework
for statistics, we also need Histograms. These are needed for range

non-uniform distribution of data.
