Jihoon Son commented on TAJO-1410:
----------------------------------
My major concern was the result size. Even though the scale factor is 1, I
thought that the result size will be large.
However, it was not true. I ran DS queries which do not involve the limit
clause with pgsql. Among them, only two queries emit results more than 1000
lines (Q2: 2513, Q71: 1043). Of course, the result size will be different with
the different parameters. However, it wouldn't be greatly different from what I
got.
So, I agree with you. More specifically, verifications on the query plan will
be much helpful, definitely.
Let's start again.
> TPC-DS TestCase
> ---------------

> Key: TAJO-1410
> URL: https://issues.apache.org/jira/browse/TAJO-1410
> Project: Tajo
> Issue Type: Test
> Reporter: Hyoungjun Kim
> Assignee: Hyoungjun Kim
> Priority: Minor
> Attachments: Tajo TPC-DS.pdf
>
>
> There is no TPC-DS TestCase in the current source code. It is difficult to
> make small TPC-DS dataset because TPC-DS is more complex than TPC-H. I
> propose TPC-DS TestCase as the followings:
> - The default build doesn't execute TPC-DS test case.
> - Add new maven profile 'tpcds-test' for TPC-DS test. If someone want to run
> TPC-DS test, run the next command.
> {noformat}
> mvn -Ptpcds-test -Dtpcds.gen.data=true
> -Dtpcds.generator=/tmp/tpcds-kit-master/tools/dsdgen
> -Dtpcds.data.dir=/tmp/tpcds install
> {noformat}
> - If tpcds.gen.data is true, The build script calls TPC-DS tool to generate
> test set with scale factor 1. TPC-DS tool should be installed in the test
> machine. Test data is located at tpcds.data.dir.
> - If test data is already exists in the test machine, set 'tpcds.gen.data'
> property false and set 'tpcds.data.dir' property with data directory.
