             Summary: Rya Mongo Blows up on Large result sets
                 Key: RYA-313
                 URL: https://issues.apache.org/jira/browse/RYA-313
             Project: Rya
          Issue Type: Bug
          Components: dao
    Affects Versions: 3.2.10
         Environment: Mongo DB with Rya 3.2.11-SNAPSHOT with a lot of data in Rya
            Reporter: Aaron Mihalik
            Assignee: Andrew Smith


Simple queries that return a lot of results fail because mongo is trying to send all of the results back at once.  For instance, if I have a lot of data and run something like:

'''
SELECT * WHERE 
{
	?s a ?t.
}
'''

I will get this exception.

Caused by: com.mongodb.MongoCommandException: Command failed with error 16389: 'aggregation result exceeds maximum document size (16MB)' on server localhost:27017. The full response is { "ok" : 0.0, "errmsg" : "aggregation result exceeds maximum document size (16MB)", "code" : 16389 }

I think we need to toss in a "AggregationOptions with Batch = 1000", but I couldn't get that to work immediately.  Somebody with more mongo experience needs to look at this.
