We've been using MapReduce for App Engine for a couple of different jobs. Typically, we use 8 shards (the default), but it seems that only 3, sometime 4, of the shards have any items in them? E.g., we're currently running one job and three of the shards have >218,000 items processed, but the other 5 shards appear to have zero.
I can understand that a particular key distribution would have different amounts in each shard, but with so many at zero, I suspect there is something else happening? BTW, we have applied the mapreduce-recommended __key__ DESC index, but we still see this strange shard distribution. Is anyone else seeing this? j -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
