SQL performance with Partitions

edited Feb 24, 2020 4:00AM in Database Administration (MOSC) 1 commentAnswered

HI,

I've a question here.

My DB version is 11.2.0.4 and we have few big tables in TB and each table is having around 1000 partitions and 150k sub partitions.

Currently i can see from all these tables there are around 700k subpartitions that are having zero rows and increasing more on daily basis.

Will there be any SQL performance impact if we have such many zero sub partitions?

These partitions are divided based on Hash partitioning.

Thanks

Hemanth
