Subject [jira] [Commented] (GIRAPH-204) Writables don't promote and that's quite suboptimal
Date Thu, 28 Jun 2012 18:04:44 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-204?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13403308#comment-13403308

Eli Reisman commented on GIRAPH-204:
------------------------------------

I like this idea a lot. Strongly typed IO would still be available for experienced users,
we need more explicitly-named IO formats and other things in this codebase to just get new
users up and running with very shallow learning curve. End users should think about algorithms
only, all other headaches should be under the hood whenever possible.

> Right now all our in/outputformats have to be exactly type conformant.  This means that
spitting an IntWritable to an OutputFormat causes a runtimeexception.  We either need to make
sure the formats are lowest-common-denominator, or are able to correctly handle reasonable
type sloppiness.
