> 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. We rely on this to implement local secondary index with data types.
