Hi list, I have a non-trivial map reduce query which traverses links between objects across several map phases, constructing a composite object enroute. One of our links is one-to-many, so I use a reduce phase to flatten my set of objects at the end.
Would a query of this type be better done as a smaller M/R query to get the base set of objects, and then multiple concurrent gets for the related objects? Is it sensible to do map reduce jobs with many map and reduce phases? I appreciate this question is somewhat open ended, but any input would be welcome.
