Jonathan Ellis commented on CASSANDRA-1651: ------------------------------------------- bq. the "right" way is to wrap segments of the buffer the reader is filling admittedly this is a much bigger change and should probably be split into another ticket. > Improve read performance by using byte array slabs > -------------------------------------------------- > > Key: CASSANDRA-1651 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1651 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: T Jake Luciani > Priority: Minor > Attachments: 1651_v1.txt > > > Now that the code has switched to byte buffers internally, it should be > possible to improve read performance by reducing the number of byte array > allocations. > This patch accomplishes this by and re-using sections of a larger byte array > slab. > I've benchmarked it locally and seen a slight improvement on reads, a larger > scale benchmark should be performed. > Also the size of a slab can be configured in cassandra.yaml -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
