Todd Lipcon resolved HDFS-3053. ------------------------------- Resolution: Duplicate looks like Dhruba filed this at the same time I did. Resolving as dup of HDFS-3051 > Support for true zero-copy (mmap-based) reads > --------------------------------------------- > > Key: HDFS-3053 > URL: https://issues.apache.org/jira/browse/HDFS-3053 > Project: Hadoop HDFS > Issue Type: New Feature > Components: hdfs client > Reporter: Todd Lipcon > > Continuing a discussion started in HDFS-2834, it would be slick to provide > support for a true zero-copy read API. In this style API, rather than having > the user pass buffers to read into, the DFS client would provide buffers to > the user. This allows the client to pass slices of mmaped blocks, for > example, which can cut one or two copies out of many read scenarios. -- This message is automatically generated by JIRA.
