Michael Stack commented on HBASE-23055:
---------------------------------------
Kicking this one again. Simplified the patch (#995). Removes the bit that had
us asking Master for table state. Instead, added to Registry querying
hbase:meta table state. ZKAsyncRegistry has added an implementation that
queries mirrored table state out of zk. If you want to edit meta, currently
MirroringTableStateManager must be enabled (default). MTSM is to be removed in
hbase3. Follow-on is alternate registry implementation for hbase3 (likely built
on the incoming Master-based Registry work).
Want to include this in hbase-2.3.0.

> hbase:meta is currently hardcoded. Its schema cannot be change.
> This issue is about allowing edits to hbase:meta schema. It will allow our
> being able to set encodings such as the block-with-indexes which will help
> quell CPU usage on host carrying hbase:meta. A dynamic hbase:meta is first
> step on road to being able to split meta.
