Just in case you've didn't have a link to the announcement they're
making this morning...

Looks like the new announcement is DynamoDB. It's already available
in the console and has been speculated before

Any idea how DynamoDB is different from other NoSQL solutions?

[Rob Bailey]

I had the same question.  This is Amazon's stated difference between Dynamo and Simple (taken from http://aws.amazon.com/dynamodb/ , just in case SOPA is watching):

"Both services are non-relational databases that remove the work of database administration. Amazon DynamoDB focuses on providing seamless scalability and fast, predictable performance. Amazon DynamoDB automatically manages the spreading of your data and workload over a sufficient number of servers to meet your scaling requirements. There is no limit on the amount of data you can store in an Amazon DynamoDB table and you can grow the request capacity to the level that you need. On the other hand, Amazon SimpleDB is a good fit for lower-scale workloads that require query flexibility. Amazon SimpleDB automatically indexes all item attributes and supports greater query functionality than Amazon DynamoDB. However, a table in Amazon SimpleDB has a size limit of 10 GB and is limited in the request capacity it can achieve. You can manually partition your data over additional SimpleDB tables if you need additional scale. Amazon CTO Werner Vogels' DynamoDB blog post provides additional context on the evolution of non-relational database technology at Amazon."

I haven't used any other no-sql solutions.  Anyone know about BigTable or etc. and others and their limitations?

That is good information. Thanks for the link.

Their marketing video states that DynamoDB runs on systems with solid state drives for performance.  Nifty.
