> HBASE-11288 'Splittable Meta' progress keeps getting hung up on how to cache the 'root' table – the first table in the hierarchy of lookups locating user-data in a Table Region. The 'root' table is not splittable by design so its load can not be spread about the cluster by splitting the hot Region as we would usually do.
> This issue is about listing out requirements, sketching possible approaches, and then getting agreement ahead of implementation as subtasks.
> In particular, an approach that would work whether the Region to be cached is master-based or hosted by a RegionServer (see design attached to HBASE-11288 for elaboration) would be preferred since then we can separate discussion of cache from the HBASE-11288 'split meta' discussion.
