> At the beginning of recovery, master can send lease recovery requests
> concurrently for outstanding WAL files using a thread pool.
> Each split worker would first check whether the WAL file it processes is
> closed.
> Thanks to Nicolas Liochon and Jeffery discussion with whom gave rise to this
> idea.
