----------------------------------------------
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.
