> Assume we use '5' as the delimiter, there are rowkeys: row1 is smaller than
> row2
> {code:java}
> row1: 12345xxx
> row2: 1235xxxx{code}

> are
> {code:java}
> row1's key for bloom filter: 1234
> row2's key for bloom fitler: 123{code}
> The row1's key for bloom filter is bigger than row2. Then
> BloomContext#sanityCheck will failed.
