There was already had DynamoDB Auto Scaling to achieve that. Main benefit of DynamoDB On-Demand from my point of view is:
- easier setup (a single setting instead of configuring auto scaling rules and policies for the table and all its indicies)
- possibly cheaper (depends on the not yet published details of the per-request pricing)
- jedberg 8y agoAuto scaling lagged though. And you still had to guess at the base level. They mentioned in the keynote that this is a big improvement over auto scaling.
- supernovagu 8y agoI am puzzled by this statement: Tables using on-demand mode support all DynamoDB features (such as encryption at rest, point-in-time recovery, global tables, and so on) with the exception of auto scaling, which is not applicable with this mode.

Does it mean auto scaling is no longer needed, or it won't happen in this mode (some hidden fixed capacity?)
- Dunedan 8y agoWith DynamoDB On-Demand AWS handles scaling transparently for the customer. So they'll definitely scale, but as a customer you shouldn't notice it. I'm quite curious how that works out in practice with rapidly changing request rates.
