Subject [jira] [Commented] (CASSANDRA-10322) skipBytes is used extensively, but is slow
Date Wed, 16 Sep 2015 18:33:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14790883#comment-14790883

Aleksey Yeschenko commented on CASSANDRA-10322:
-----------------------------------------------

I don't feel too strongly about it, so won't fight if there is any disagreement, but I too
have a moderate preference towards 'backporting' to 2.2.

> 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}}
