------------------------------------------
Summary: Thrift deserialization of Partition objects should intern
fields
Key: HIVE-19041
URL: https://issues.apache.org/jira/browse/HIVE-19041
Project: Hive
Issue Type: Improvement
Components: Metastore
Affects Versions: 2.3.2, 3.0.0
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
When a client is creating large number of partitions, the thrift objects are
deserialized into Partition objects. The read method of these objects does not
intern the inputformat, location, outputformat which cause large number of
duplicate Strings in the HMS memory. We should intern these objects while
deserialization to reduce memory pressure.
