Pavel Yaskevich commented on CASSANDRA-1714:
--------------------------------------------
I have tried with -S 2048 but will try with 16384 soon, I have discovered
strange issue with my changes - stress can't read portion of the inserted keys
after one of the inserts, working on that now.
> zero-copy reads
> ---------------
>
> Key: CASSANDRA-1714
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1714
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Jonathan Ellis
> Assignee: Pavel Yaskevich
> Fix For: 0.7.1
>
> Attachments: CASSANDRA-1714.patch, zerocopy.txt
>
> Original Estimate: 32h
> Remaining Estimate: 32h
>
> Since we are already using mmap'd ByteBuffers in MappedFileDataInput we
> should be able to do zero-copy reads (via buffer.slice()), which would give
> us better performance than CASSANDRA-1651 without having to worry about
> buffer management.
