Jonathan Ellis commented on CASSANDRA-6936:
-------------------------------------------
I'm not sure this is worth the pain tbh. Some common comparisons (notably
text) are already byte-comparable and others (int32) are close enough that
speed gain will likely be negligible.
Maybe a time will come where comparisons are our main bottleneck but we're not
there atm and future storage changes will probably impact this as well.
I'm inclined to close as Later.

> Key: CASSANDRA-6936
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6936
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Benedict
> Labels: performance
> 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.
