Michael Stack commented on HBASE-24580:
---------------------------------------
[~ndimiduk] notes this implemented already storing to a dedicated file,
HBASE-20727. Move it into our master local region then (or resolve this issue)
> Persist map of regions-to-last-flush-sequenceid across restarts

> A nice suggestion by our [~ndimiduk] was that we persist the
> last-successful-flush-sequenceid per region kept up by an in-memory map in
> Master. We could add it to our nice new general local master store. On
> restart, could rehydrate the map. Would be helpful on cold start in
> particular, especially if a big backlog of WALs to replay.
