[jira] [Created] (HIVE-10175) Tez DynamicPartitionPruning lacks a fast-path exit for large IN() queries

Gopal V created HIVE-10175:
------------------------------

             Summary: Tez DynamicPartitionPruning lacks a fast-path exit for large IN() queries
                 Key: HIVE-10175
                 URL: https://issues.apache.org/jira/browse/HIVE-10175
             Project: Hive
          Issue Type: Bug
          Components: Tez
    Affects Versions: 1.2.0
            Reporter: Gopal V
            Priority: Minor


TezCompiler::runDynamicPartitionPruning() calls the graph walker even if all tables provided to the optimizer are unpartitioned temporary tables.

This makes it extremely slow as it will walk & inspect a large/complex FilterOperator later in the pipeline.
