I'm attempting to use mapreduce for app engine as presented at I/O 2010. I just noticed the following warning message in our logs (on / mapreduce/command/start_job):
Cannot create accurate approximation of keyspace, guessing instead. Please address this problem: no matching index found. This query needs this index: - kind: AccountKeyword properties: - name: __key__ direction: desc This seems to suggest that there is no (desc) index for the key of our Model. However, isn't this created automatically? Indeed, I can't even think of a way to _not_ have it created (i.e., I can't think of a way to specify indexed=False for the key). Is this an error in reporting, or is something very wrong with our Datastore? Thanks, j -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
