[jira] [Created] (IMPALA-12601) Add a fully partitioned TPC-DS dataset for planner tests

-------------------------------------

             Summary: Add a fully partitioned TPC-DS dataset for planner tests
                 Key: IMPALA-12601
                 URL: https://issues.apache.org/jira/browse/IMPALA-12601
             Project: IMPALA
          Issue Type: Test
          Components: Infrastructure
    Affects Versions: Impala 4.3.0
            Reporter: Riza Suminto
            Assignee: Riza Suminto


testdata/datasets/tpcds only have store_sales table fully-partitioned and leave other facts table unpartitioned. This is probably intended for faster data loading during test. However, this is not an accurate reflection of larger scale TPC-DS dataset where all facts tables are partitioned. Impala planner may change the detail of query plan if partition column exist.

Today, Impala can load a small scale, fully-partitioned TPC-DS dataset in parquet format to minicluster in reasonable speed. We should consider adding such test db and change PlannerTests to test against that fully-partitioned db instead of current tpcds/tpcds_parquet test db.
