Very good news.
More about it here: http://research.microsoft.com/en-us/news/features/hekaton-122012.aspx

This will be a big boost for the transient pieces of OLTP applications. Can’t wait to start using this!

Do you expect it will be included in SQL Server 2012 R2 ( due next year if I’m correct) , or will we need to wait longer ?

Snehal, I agree with you. That was my first reaction. It is implemented as a fancy DBCC PINTABLE with modification to locking which bite us in the rear during high concurrency.
I wonder what they did regarding compilation related lock thresholds. If transaction processing increases by an order of magnitude will we be killed by dynamic queries for example?

Thanks for such a great news.
As Microsoft discontinued one such command like DBCC PINTABLE, however it required manual analysis and there were prons and cons also. Great idea to include such a functionality to existing arsenal.

And also, here is another question: will Hekaton be used in SQL Azure?
I did some tests of the Azure performance, and it seemed in a critical state: about 1 second to establish a connection and optimization speed and storage speed which was competing with my laptop’s performance. (Here is the test results: http://sqlconcept.com/2012/12/20/analysis-of-sql-azure-performance-tests/)
I really hope Azure gets better, so we can use it.

Interesting.
This seems to be “a day late and a dollar short”, as the expression goes. But still it is better to have it late than never.
I wonder, though, if these features will be specific to a certain edition; in other words, is it going to cost extra for a well-performing SQL Server? (We know from past experiences that some editions perform better than others – take the Resource Governor for example.)

Can I be one of the testers for the Hekaton?
