---------------------------------------
Summary: Query compilation: PartitionDesc can reduce the number of
table metadata calls
Key: HIVE-15315
URL: https://issues.apache.org/jira/browse/HIVE-15315
Project: Hive
Issue Type: Improvement
Components: Metastore
Reporter: Rajesh Balamohan
Assignee: Rajesh Balamohan
Priority: Minor
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/plan/PartitionDesc.java#L88
When compiling the query with partition dataset, partitiondesc ends getting
table metadata from metastore lot many times. This can be optimized to reduce
the number of hits to the database.
