Todd Lipcon created HDFS-3529: --------------------------------- Summary: Use direct buffers for data in write path Key: HDFS-3529 URL: https://issues.apache.org/jira/browse/HDFS-3529 Project: Hadoop HDFS Issue Type: Improvement Components: data-node, performance Affects Versions: 2.0.0-alpha Reporter: Todd Lipcon Assignee: Todd Lipcon
The write path currently makes several unnecessary data copies in order to go to and from byte arrays. We can improve performance by using direct byte buffers to avoid the copy. This is also a prerequisite for native checksum calculation (HDFS-3528) -- This message is automatically generated by JIRA.
