Jihoon Son commented on TAJO-1410:
----------------------------------
Do you mean verification of the query results? If so, it makes sense. However,
there are still limitations with the data set of the scale factor of 1. For
example, it may be difficult to find specific bugs which can be found in
cluster environments.
So, IMHO, if someone wants to exactly measure the coverage, he or she should
run DS benchmarks with sufficiently large data rather than the scale factor of
1 in real environments.
Except result verification, this patch does just automatic data generation and
query execution. If you want to provide an easy way to measure DS coverage, I
think it would be better to maintain a separate repository.
I wonder why we should maintain it within our source tree.
> TPC-DS TestCase

>
> 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.
