Summary: 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
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.
