Alex Baranau commented on HBASE-7892:
-------------------------------------
Oh, I must have confused javadoc with the HBASE-6618 one (i.e. improved).
I guess you logic could be applied to the HBASE-6618 too. Though I don't see
problems with requiring \x00 at non-fixed positions if that makes the algo of
aplying filter simpler/more efficient.
I believe current implementation should be patched with HBASE-6618, so I'd ask
you to base you patch on it. Could you take a look if it still sensible in the
context of HBASE-6618 please?

> An actual case can be:
> we want to match "a?ex", so we give "a?ex" as input of "key bytes", and
> "0100" as input of "meta bytes".
> if we start with row = "\0\0\0\0", the next hint would turn out to be "a?ex"
> while actually the right hint should be "a\0ex".
