> 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.
