Brandon Williams commented on CASSANDRA-1714: --------------------------------------------- I see around a 20% increase in reads against a single node with this patch. > 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-1714-0.7.patch, CASSANDRA-1714-v2.patch, > CASSANDRA-1714-v3.patch, CASSANDRA-1714-v4-trunk.patch, CASSANDRA-1714.patch, > zerocopy.txt > > Original Estimate: 32h > Time Spent: 32h > Remaining Estimate: 0h > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
