Sean Busbey commented on HBASE-22938:

Can we aim for a design doc once there's consensus in the discussion?

* What do upgrades look like
* This will need splittable meta I think?

> Fold all the system tables to hbase:meta

> We could add a special prefix in the row key for different system tables, and 
> make a special family for it. For example, for all the records in hbase:acl, 
> we could introduce a prefix like ':::acl:::', since we do not allow ':' in 
> either namespace or table name, so it will not conflict with the existing 
> table related records. And the family could be namd as 'acl'.
> And we could make a special split policy that only splits at these special 
> prefixs, so it will not break any assumptions so far, as all the records for 
> the 'system table' are in the same region.

> And I think there are also other advantages, for example the start up logic 
> can be greatly simplified.
