-------------------------------------
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.
