This issue is similar to HIVE-25178 and does the same 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
> Priority: Major
>
> 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.
