Folke Behrens commented on CASSANDRA-1282:
------------------------------------------
Very true. By the way, BytesType needs to be fixed, too. CASSANDRA-242 dropped
the initial length == 0 check and now BytesType allows null values.
> NumericType: comparator for integers of fixed and arbitrary length

> Patch introduces a new column comparator: NumericType. It can compare signed
> integer values of fixed (int, long) and arbitrary length (BigInteger). Both
> can be mixed. Leading zero bytes or 0xFF bytes will be ignored and can safely
> be stripped on compaction.
> The trivial version uses "new BigInteger(byte[]).compareTo(new
> BigInteger(byte[]))" but it's slower and fills up memory.
> The faster version operates completely on stack and should even obsolete
> LongType.
