There was a problem hiding this comment.
Unrelated file pnpm-lock.yaml need to be removed.
I have one minor comment, overall patch LGTM.
Can you look into failed CI tests?

What changes were proposed in this pull request?
Currently, for safe mode we consider all pipelines existing in DB for safe mode exit criteria. It ma happen that, SCM has the pipelines craeted , but none of the participants datanodes ever created these datanodes. In such cases, SCM fails to come out of safemode as these pipelines are never reported back to SCM.
The idea here is to consider pipelines which are marked open during SCM startup.
