https://github.com/percona/orchestrator/pull/12 is reverted and https://github.com/percona/orchestrator/pull/15 is merged to trunk.
Orchestrator sends a lot of concurrent REPLACE/SELECT queries that create a lot of semaphore waits in MySQL starting from version 8.0.29. This is result of but also the issue with the Orchestrator, because it may perform same task better.

Expected Fix
