Jonathan Ellis commented on CASSANDRA-10322:
--------------------------------------------
All right.
> skipBytes is used extensively, but is slow

> Key: CASSANDRA-10322
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10322
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Benedict
> Assignee: Benedict
> Priority: Trivial
> Fix For: 3.0.x
>
>
> We skip a great deal to avoid materializing data. Ironically, however,
> skipping is just as (perhaps more) expensive, as it allocates a temporary
> array of the size of the number of bytes we want to skip.
> This trivial patch implements {{skipBytes}} more efficiently, and simplifies
> {{FileUtils.skipBytesFully}}
