Benedict Elliott Smith commented on CASSANDRA-6936:
---------------------------------------------------
I trust you to have made good choices, [~blambov]. I'll see if I can find some
time to get an overview the work for some high level feedback about the
serialisation format, but I haven't thought about this problem domain in a long
time so my consideration may be less valuable than you imagine. I won't likely
have the time to perform a full review either way.

> 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.
