Robert Dyer commented on HBASE-7748:
------------------------------------
Am I correct in assuming that if there is a very uneven distribution of user's,
and the region has say 5 users, but the first user in the region takes up over
half the space (and thus the split point picks that user) that this
implementation will wind up not splitting?
Wouldn't it make sense to find the row group's first row (what the current
patch does) *and* find the next group's first row and choose based on which one
gives a better split?

> DelimitedKeyPrefixRegionSplitPolicy similar to KeyPrefixRegionSplitPolicy,
> but with a delimiter for the key, instead of a fixed prefix.
> Can be used for META regions, since we are doing
> table_name,start_key,region_id.encoded_region_name.
