What will happen about transaction recovery in some situation?

I’m interested in full managed Confluent Cloud, not Platform, especially in “Dedicated Cluster”.
As far as I know, there is no info about transaction recovery in Confluent Cloud Docs.

  1. What will happen about transaction recovery when Confluence Cloud stopped by system failure? Will some transaction be recovered automatically by Confluence Cloud?

  2. What will happen about transaction recovery when Confluence Cloud faced spike and stopped in somehow?
