[~rkondakov], I've left a comment to the PR, other looks good.
> SQL regressions detection framework
> -----------------------------------
>
> Key: IGNITE-13070
> URL: https://issues.apache.org/jira/browse/IGNITE-13070
> Project: Ignite
> Issue Type: Test
> Components: sql
> Reporter: Roman Kondakov
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> We need to detect SQL regressions early. We can do it by comparing the SQL
> query performance for different Ignite versions. This test framework should
> work in the following way:
> # It starts two Ignite clusters with different versions (current version and
> the previous release version).
> # Framework then runs randomly generated queries in both clusters and checks
> the execution time for each cluster. We need to port SQLSmith library from
> C++ to java for this step. But initially we can start with some set of
> hardcoded queries and postpone the SQLSmith port. Randomized queries can be
> added later.
> # All problematic queries are then reported as performance issues. In this
> way we can manually examine the problems.
