Description OpenShift BugZilla Robot 2022-06-09 18:43:24 UTC

+++ 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

This change is transparent to end user. Mark as verified only based on regression test result with latest 4.10 TALM downstream build.

Comment 3 jun 2022-07-04 18:15:17 UTC

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.
