Range Key Querying on composed keys Re-reading your question carefully, I don't get the meaning of the relationship between userId and otherUserId ? Is it recording sthg like userA interacted with userB at some point in time ? Could you describe in details the different kind of queries you want to do (e.g. retrieve all interaction in a given period, etc) ? That would help definitely :)

Range Key Querying on composed keys Yep. Imagine your range keys ressemble "2013-03-27T00:00:00.511413+00:00::39782966765019163484612439806639178296". This way you can query with a BETWEEN("2013-01", "2013-02") condition to retrieve records matching a hash key and inserted between Jan and Feb 2013 (actually it's just a lexicographical sort condition).

boto dynamodb: is there a way to optimize batch writing? How much Write Capacity did you provision ? you mean 400 QPS throughput I guess, so if your dynamodb capacity is < 400 you'll probably get throttled requests. Did you have any before ? There is a nice graph for this in the AWS console. |

boto dynamodb: is there a way to optimize batch writing? try to call boto.utils.get_instance_metadata()['instance-id'] and compare with your boto.dynamodb.Layer2.layer1.region
