---------------------------------------
Summary: Reuse table information in SemanticAnalyzer::getMetaData
to reduce compilation time
Key: HIVE-15300
URL: https://issues.apache.org/jira/browse/HIVE-15300
Project: Hive
Issue Type: Improvement
Components: Parser
Reporter: Rajesh Balamohan
Priority: Minor
E.g Q88 in tpc-ds takes lots of time to compile and it ends up getting the
table details for the same table repeatedly. It took 20+seconds to compile the
query.
It would be good to reuse the table information in
SemanticAnalyzer::getMetadata.
