+++ This bug was initially created as a clone of Bug #2091113 +++ Description of problem: Currently TALO does 3 list operations for every reconcile call just to update its status fields that track the ACM resources it created. Even though these are namespaced query, they can be slow in large scale ZTP scenarios where we have large number of CGUs in the same namespace. More details on the impact can be found at https://issues.redhat.com/browse/CNF-5408 Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: TALO should do this only when it's creating new ACM objects. Additional info:
This change is transparent to end user. Mark as verified only based on regression test result with latest 4.10 TALM downstream build.
This has been verified in the scale lab. With the fix, we can sustain 480 clusters per hour (40 clusters every 5 minutes) for ZTP deployment with du profile.
