Subject [jira] [Created] (CASSANDRA-6936) Make all byte representations of types comparable by their unsigned byte representation only
Date Wed, 26 Mar 2014 18:49:18 GMT
Benedict created CASSANDRA-6936:
-----------------------------------

             Summary: 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
            Assignee: Benedict
             Fix For: 3.0


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.
