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.
Oh man if he joined any university and taught databases I would drop everything to take that course. What an amazing talk.
He needs to teach at the University. More useful than anything my professors taught me
University can not pay as much as aws xD.
Never saw an overview session as great as this is.
I wish I could convey technical information this succinctly and quickly.
oh my God this is great overview....
Great talk and great overview. Just how many database types does one organization need!?!?! LOL :-)
Awesome, thanks
Best speaker
Excellent talk
1:36 Larry Ellison keeps poking at them that they still use Oracle databases. Guess they are finally jumping ship.
will the slide deck be available?
