Why doesn't dynamodb support simple aggregations like mongodb does? I understand that table joins would be very inefficient accross multiple shards. However, I would have thought that aggregations would be more efficient....
I think he said it - DynamoDB is for queries that you know before hand. Aggregations kind of bleed into that ad hoc style of querying that requires something else
@@alexnarayanstechandetc Not necessarily. If you know the access pattern of the aggregation, you can pre-aggregate in DynamoDB. That's the DynamoDB's way of doing aggregation.
