------------------------------------
Summary: Add possibility to store column level statistics at the
table level
Key: HIVE-29824
URL: https://issues.apache.org/jira/browse/HIVE-29824
Project: Hive
Issue Type: New Feature
Reporter: Thomas Rebele
When certain column level statistics (e.g., histograms) are stored at the
partition level, they require a lot of disk space. Hive should provide a way so
that the user can decide to store the statistics at the table level instead.
It needs to be decided whether to configure the property globally, for a table,
or a particular column.
This would provide a workaround for the KLL instability caused by the non-fixed
seed when merging KLL datasketches.
