Ad hoc queries using SQL like syntax. No need to define indexes. Javascript execution within database. Stored procedures, triggers and functions can be written with Javascript. "All JavaScript logic is executed within an ambient ACID transaction with snapshot isolation. During the course of its execution, if the JavaScript throws an exception, then the entire transaction is aborted." Pricing is based on "capacity units". Starts with $22.50 per month (this includes 50% preview period discount). One capacity unit (CU) gives 10GB of storage and can perform 2000 reads per second, 500 insert/replace/delete, 1000 simple queries returning one doc. In order to see pricing details, change the region to "US West": http://azure.microsoft.com/en-us/pricing/details/documentdb/ http://azure.microsoft.com/en-us/pricing/details/documentdb/ Very interesting addition to Microsoft offering. I was actually just yesterday wondering if they have any plans for this kind of service. Table Storage is quite primitive and Azure SQL on the other hand gets expensive when you have lots of data. One potential "problem" with this is the bundling of storage capacity and processing power. If I understand this correctly, I would need to buy 10 CUs per month to store 100GB of data even if I'm not very actively using that data.
