nkeywal commented on HBASE-7213:
--------------------------------
To me, there are some stuff that are nice to have in multiwal but very useful
here:
- it's better to have only one table in the wal with ".meta."
- it's would be great to be able to configure the replication factor for this
wal
- having a separate wal for meta should be the only option (it could make sense
short term to have it as an option for safety, but it would be temporary)
- there is no real split of the .meta. wal (at least conceptually: all regions
ends up on the same server..). There is some room for (premature?) optimization
there.
> Have HLog files for .META. edits only

> written. This jira is to track an implementation of that.
