[jira] [Created] (CASSANDRA-10322) skipBytes is used extensively, but is slow

Benedict created CASSANDRA-10322:
------------------------------------

             Summary: 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: Minor
             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}}
