> Affects Versions: 0.5.0
> Reporter: Richard Kasperski
> Assignee: Runping Qi
>
> There are many tasks where I need to have finer control over the ordering in
> the reduce than a sort on a single key provides. Most of these situations
> arise when a merge two sources of data and am attaching a single instance of
> one source to multiple instances of a second source. I know that I can read
> all the the records with a single key. It's possible that there might be many
> millions of these making memory demands that cannot be satisfied.
