-- This is more cleaner approach for writing a test that relies on system.query_log/query_thread_log.
|
|
--
|
|
-- It uses current database, and since clickhouse-test will generate random for
|
|
-- each run you can run the test multiple times without worrying about
|
|
-- overlaps.
|
|
--
|
|
-- There is still event_date/event_time filter for better performance
|
|
-- (even though this is not relevant for runs on CI)
