-----------------------------------
Summary: Enhance logging in TableAccessInfo
Key: HIVE-3968
URL: https://issues.apache.org/jira/browse/HIVE-3968
Project: Hive
Issue Type: Improvement
Components: Query Processor
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
Based on what is currently available in the TableAccessInfo we can infer when
it would be a good idea to add bucketing/sorting metadata for tables. However,
we can't easily tell if we're already getting the benefits of bucketing/sorting.
This information can be improved by
a) storing the input table/partition objects so that we can tell if the
tables/partitions are already bucketed/sorted
b) running the TableAccessAnalyzer after the logical optimizer, so that we can
tell from the operators whether or not we are already getting benefits
(bucketed/sort merge map joins or map group bys)
