>          Components: SQL
>    Affects Versions: 3.1.1

> When we have a table with a lot of partitions and there is no way to filter it on the MetaStore Server, we will get all the partition details and filter it on the client side. This is slow and puts a lot of pressure on the MetaStore Server.
> We can first pull all the partition names, filter by expressions, and then obtain detailed information about the corresponding partitions from the MetaStore Server.
