Reducer shard with too many values

[Ricardo Diaz]

Hello Guys,

Great work ! on mapreduce framework as well as new changes in the API.

May be this is a naive question: What the framework does if a reducer shard has to many values for a given key (after shuffling of course) or this is no going to happen by design ?

Thank you,

Ricardo.

Use a combiner. https://code.google.com/p/appengine-mapreduce/source/browse/trunk/python/src/mapreduce/mapreduce_pipeline.py#161
