> UTF8Type.compare() is slow and dangerous
> ----------------------------------------

> Key: CASSANDRA-1232
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1232
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Folke Behrens

> Fix For: 0.6.4

>
> UTF8Type converts both byte arrays into Strings and then compares them. This
> is unnecessary and slow because UTF-8 encoded Strings are already directly
> comparable. Higher codepoints yield higher initial and subsequent bytes. One
> can safely use BytesType.compare() for UTF-8. Maybe UTF8Type should be a
> subclass only overriding getString().
> BTW, It's also dangerous to ignore invalid byte sequences. At this point the
> byte array should contain valid UTF-8.
