-----------------------------------
Assignee: (was: Sergey Shelukhin)
> metastore server can cache pruning results across queries
> ----------------------------------------------------------
>
> Key: HIVE-5171
> URL: https://issues.apache.org/jira/browse/HIVE-5171
> Project: Hive
> Issue Type: Improvement
> Reporter: Sergey Shelukhin
>
> Partition pruning results are cached during a query (SemanticAnalyzer and
> ParseContext are the scope).
> We could also cache them between queries in MetaStore, which would be
> especially useful if metastore server is remote and thus long-lived/shared
> between clients.
> It may be more complex than it seems due to OOM potential. Also the key would
> need to be changed since the same expression string that is currently used
> may mean different things for different queries.
