>
> While the KRaft controller is making writes back to ZK during the migration,
> we need to handle the case when a snapshot is loaded. This can happen for a
> number of reasons in KRaft.
> The difficulty here is we will need to compare the loaded snapshot with the
> entire state in ZK. Most likely, this will be a very expensive operation.
> Without this, dual-write mode cannot safely tolerate a snapshot being loaded,
> so marking this as a 3.5 blocker.
