Nick Dimiduk commented on HBASE-9466:
-------------------------------------
More that just filtering with Kerberos, if the RS knowns a Region is in RO
mode, it can skip initialization of write-path components to save resources.
This would also allow the RO regions to be served by all three favored notes.

> Can we provide a read-only mode for a table? write to the table in read-only
> mode will be rejected, but read-only mode is different from disable in that:
> 1. it doesn't offline the regions of the table(hence much more lightweight
> than disable)
> 2. it can serve read requests
