A Tour of Amazon DynamoDB Features and API

Mathias Meyer’s walk through the DynamoDB features and API with commentary:

Sorted range keys, conditional updates, atomic counters, structured data and multi-valued data types, fetching and updating single attributes, strong consistency, and no explicit way to handle and resolve conflicts other than conditions. A lot of features DynamoDB has to offer remind me of everything that’s great about wide column stores like Cassandra, but even more so of HBase. This is great in my opinion, as Dynamo would probably not be well-suited for a customer-facing system. And indeed, Werner Vogel’s post on DynamoDB seems to suggest DynamoDB is a bastard child of Dynamo and SimpleDB, though with lots of sugar sprinkled on top.

Think of it as an extended, better articulated and closer to the API version of my notes about Amazon DynamoDB.
