> Another major use of HRegion methods in Phoenix is locking. HBase has
> proposed adding a Region interface, which would be a supportable subset of
> HRegion methods applications like Phoenix may need. If it exposes read
> (region) and write (row) locks then we can use them:
> - Where we lock META rows when making transactional changes to system tables
> - When we process aggregates, sequences, and index or system table updates
