[jira] [Created] (HIVE-25187) Reduce number of getPartition calls
during loadDynamicPartitions for Managed Tables
Narayanan Venkateswaran created HIVE-25187:
----------------------------------------------
Summary: Reduce number of getPartition calls during loadDynamicPartitions for Managed Tables
Key: HIVE-25187
URL: https://issues.apache.org/jira/browse/HIVE-25187
Project: Hive
Issue Type: Bug
Components: Hive
Reporter: Narayanan Venkateswaran
When dynamic partitions are loaded, Hive::loadDynamicPartition loads all partitions from HMS causing heavy load on it. This becomes worse when large number of partitions are present in tables.
Only relevant partitions being loaded in dynamic partitions can be queried from HMS for partition existence.
