> The current DelimitedKeyPrefixRegionSplitPolicy split policy is not flexible
> enough to describe the split point prefix in some case. A regex based split
> policy is proposed, for example:
> ^[^\x00]+\x00[^\x00]+\x00
> means the split point will always be truncated to a prefix at the second \0
> char.
> The binary string support is quite useful when the rowkey encoded by a common
> data access library instead of concatenated manually by application developer.
