Summary: Lazy evaluate HiveMetastore::fireReadTablePreEvent table computation Key: HIVE-22725 URL: https://issues.apache.org/jira/browse/HIVE-22725 Project: Hive Issue Type: Improvement Reporter: Rajesh Balamohan "TransactionalValidationListener" gets added in the pre-event listeners of HMS by default. [https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L559] This causes issue in short select queries, as table details are computed for any partition lookups. [https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L4984] It would be good to lazy evaluate table lookup in this codepath. -- This message was sent by Atlassian Jira (v8.3.4#803005)
