> 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.
