Aleksey Yeschenko commented on CASSANDRA-6936:
----------------------------------------------

Fixed, but not single-byte, because BooleanType would accept any BB as long as 
it's 0 or 1 byte of size, and it can't be changed for backward-compatibility 
reasons :\

> Make all byte representations of types comparable by their unsigned byte 
> representation only

> This could be a painful change, but is necessary for implementing a 
> trie-based index, and settling for less would be suboptimal; it also should 
> make comparisons cheaper all-round, and since comparison operations are 
> pretty much the majority of C*'s business, this should be easily felt (see 
> CASSANDRA-6553 and CASSANDRA-6934 for an example of some minor changes with 
> major performance impacts). No copying/special casing/slicing should mean 
> fewer opportunities to introduce performance regressions as well.
> Since I have slated for 3.0 a lot of non-backwards-compatible sstable 
> changes, hopefully this shouldn't be too much more of a burden.
