---------------------------------
Summary: ExprNode/Sarg changes to support values supplied during
query runtime
Key: HIVE-15270
URL: https://issues.apache.org/jira/browse/HIVE-15270
Project: Hive
Issue Type: Improvement
Reporter: Jason Dere
Assignee: Jason Dere
Infrastructure changes to support retrieval of query-runtime supplied values,
needed for dynamic min/max (HIVE-15269) and bloomfilter join optimizations.
- Some concept of available runtime values that can be retrieved for a
MapWork/ReduceWork
- ExprNode/Sarg changes to pass a Conf during initialization - this allows the
expression to retrieve the MapWork at query time (using
Utilities.getMapWork(Configuration)) to access runtime-supplied values.
- Ability to populate the runtime values in Tez mode via incoming Tez edges
