Allow Replicated Table Drop After Failed Attempt Due to ZooKeeper Session Expiration
Allow to drop Replicated table if previous drop attempt was failed due to ZooKeeper session expiration. This fixes #11891. #14926 (alexey-milovidov).
Why it matters
This feature addresses the problem where a Replicated table could not be dropped if a prior drop operation failed because of a ZooKeeper session expiration, preventing users from cleaning up or removing such tables. It improves reliability and manageability of Replicated tables by allowing a drop retry after transient ZooKeeper issues.How to use it
Users can simply retry theDROP TABLE command on a Replicated table that previously failed to drop due to ZooKeeper session expiration. There is no special configuration needed; the system now handles these cases gracefully.
