[jira] [Created] (SPARK-35437) Hive partition filtering client optimization

dzcxzl created SPARK-35437:
------------------------------

             Summary: Hive partition filtering client optimization
                 Key: SPARK-35437
                 URL: https://issues.apache.org/jira/browse/SPARK-35437
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.1.1
            Reporter: dzcxzl


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.
