             Summary: Distributed cache of root table data (ROOT/hbase:meta)
                 Key: HBASE-24723
                 URL: https://issues.apache.org/jira/browse/HBASE-24723
             Project: HBase
          Issue Type: Bug
            Reporter: Michael Stack


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.
