A feature request (I see that Werner is reading this message thread): for development it woud be very nice to have the Java AWS SDK have a local emulation mode for SimpleDB and DynamoDB. This would allow development while flying or otherwise off the Internet. Similar functionality as AppEngine's local dev mode.

Well, Azure has been offering a similar NoSQL service for a few years now. http://sigops.org/sosp/sosp11/current/2011-Cascais/printable...
No. They offer the equivalent of Amazon S3, SimpleDB and SQS, but nothing comparable to this
Can you elaborate how this is different and not comparable? Azure's table service offers the same automatic partition management, unlimited per-table scalability, composite keys, range queries, and availability guarantees. The linked paper goes into more details.

#33I work for a popular startup that has been privately testing dynamo for the last few months.
It's a fantastic product and even while in private beta has been stable and well supported.

Since HN doesn't show vote totals I wanted to chime in and say this would be really useful to me as well.

Which game?

How is this vastly different to Azure Tables?

#38This looks like a great service - there are some really interesting ideas here. The provisioned throughput is a great idea. It's interesting to see it runs on SSDs as well, I wonder if its storage is log based like LevelDB. The composite hashed indexes are really interesting as well - I guess they partition the index across nodes, and each node maintains a range of the sorted index. It'll be interesting to see how usable that is in practise.
I read with interest Steve Yegge's mistakenly-leaked email about the oppressive conditions for engineers at Amazon. It's hard to reconcile with the sort of innovation they consistently show.

#39What's the concern for lock-in here - how difficult with DynamoDB be to migrate away from? Amazon seems to be increasingly catching the App Engine Syndrome, though to be fair, it's been mostly network traffic-style functionality in the past.

Not really if you pay attention to the set of NoSQL DB's available already. They are just hosting their own now.
