> If I am not wrong, for system tables expect meta we still share logs with
> user regions, so even if we have some logic to assign system tables first, we
> still need wait log splitting done and we can not guarantee logs of system
> tables are split first. So there may be a blocking task that we should make
> multi-log feature having priority and write entries of system table in the
> highest priority logs. Thanks.

> This is an umbrella for working out our long term plan around how we handle
> WAL prioritization and recovery.
