    Component/s: Core

> Make all byte representations of types comparable by their unsigned byte 
> representation only
> --------------------------------------------------------------------------------------------
>                 Key: CASSANDRA-6936
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6936
>             Project: Cassandra
>          Issue Type: Improvement
>          Components: Core
>            Reporter: Benedict
>            Priority: Major
>              Labels: compaction, performance
>             Fix For: 4.x
> 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.
