Tom White updated MAPREDUCE-326: -------------------------------- Attachment: MAPREDUCE-326.pdf Here's a proposal for a binary API for review. > The lowest level map-reduce APIs should be byte oriented > -------------------------------------------------------- > > Key: MAPREDUCE-326 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-326 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Reporter: eric baldeschwieler > Attachments: MAPREDUCE-326.pdf > > > As discussed here: > https://issues.apache.org/jira/browse/HADOOP-1986#action_12551237 > The templates, serializers and other complexities that allow map-reduce to > use arbitrary types complicate the design and lead to lots of object creates > and other overhead that a byte oriented design would not suffer. I believe > the lowest level implementation of hadoop map-reduce should have byte string > oriented APIs (for keys and values). This API would be more performant, > simpler and more easily cross language. > The existing API could be maintained as a thin layer on top of the leaner API. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
