Branimir Lambov commented on CASSANDRA-6936:
--------------------------------------------
[~benedict], I think it would be best if you review this, so that we can
incorporate any ideas you may have into the encoding while it still isn't used
in any persisted data and we can freely modify it. Do you think you will have
the time to do so?

> 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.
