Subject [jira] [Commented] (HDFS-7445) Implement packet memory pool in output stream in libhdfs3
Date Tue, 09 Dec 2014 01:51:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7445?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14238836#comment-14238836
] 

Colin Patrick McCabe commented on HDFS-7445:
--------------------------------------------

I don't have a strong preference, but I'd like to see us finish stuff like the hdfs.h interface
and the addition of unit tests before we start on this optimization.  I feel like this is
something we could easily do after merging to trunk.  I guess it's somewhat up to you, though.

> Implement a packet memory pool instead of allocating packet dynamically. A packet memory
pool can guard against overcommit and avoid the cost of allocation for output stream in libhdfs3.
