[jira] [Created] (HIVE-23940) Add TPCH tables (scale factor 0.001) as qt datasets

Stamatis Zampetakis created HIVE-23940:
------------------------------------------

             Summary: Add TPCH tables (scale factor 0.001) as qt datasets
                 Key: HIVE-23940
                 URL: https://issues.apache.org/jira/browse/HIVE-23940
             Project: Hive
          Issue Type: Improvement
            Reporter: Stamatis Zampetakis
            Assignee: Stamatis Zampetakis


Currently there are only two TPCH tables (lineitem, part) in qt datasets and the data do not reflect an actual scale factor. 

TPC-H schema is quite popular and having all tables is useful to create meaningful and understandable queries. 

Moreover, keeping the standard proportions allows to have query plans that are going to be meaningful when the scale factor changes and makes it easier to compare the correctness of the results against other databases.  

The goal of this issue is to add all TPCH tables with their data at scale factor 0.001 as qt datasets.
