Answer:  It currently does NOT run with 4199 enabled. 

In the future, we may be able to expose something more specific and advanced here.  Customers needing to have this level of control can use SQL Server 2012 in a Virtual Machine instead on Windows Azure.  FWIW, we have not seen this to be a significant issue on SQL Azure so far (in terms of escalated support cases).  Obviously this can change in the future.

One question I got from my recent trip was around query parallelism in WASD/SQL Azure. 

Currently WASD does not support parallel queries for user operations.  That’s not a “never” statement, more of a “right now” statement.  The initial model for databases in WASD focuses primarily on OLTP queries (which rarely if ever need to be parallel unless something is wrong).  Additionally, the commodity hardware being used for initial WASD clusters is more well-suited for OLTP than DW (though it is possible and some do try to do more IO-intensive workloads on the platform). 

One nuance to this answer is that a number of customers are employing sharding approaches for solutions on WASD, especially Software-as-a-Service (SaaS) ISVs.  These customers end up using hundreds of thousands of databases to store what might have been “one” database in an on-premise equivalent.  The net effect of using such a pattern is that you can submit multiple queries to them in parallel and these can execute concurrently across many machines.  As a result, there is a form of inter-query parallelism instead of intra-query parallelism that can be employed.  In some ways, it is actually more powerful than what we can do within a single query both because we can leverage more cores and because it is more explicit – you can somewhat “force” a notion of parallelism that is not exposed in the base product today.

Customers wishing to use traditional parallel queries have the option to use the SQL Server-in-a-VM solution that is now released on Windows Azure.

I could safely say that I have never been introduced by Robin Hood at one of my talks.  I always have so much fun at SQL Bits because they just get how to throw a fun, fun conference.  Thanks to the crew who run it, as always, for being such wonderful hosts and allowing me to speak there.

For those who are interested, the slide deck from my talk is here:

Architecting Large Scale Services on SQL Azure

I got a few questions after the talk and over email.  I will try to summarize some of those in a subsequent post.

Thanks,

Conor

I asked around a bit and, sure enough, yes we do.

Best Practice Guidance on SQL Injection Proections

1. SQLIntersection 2013, Las Vegas – week of April 7th.   (https://www.sqlintersection.com/)

2. SQLBits Spring 2013, Nottingham, UK – week of May 2nd (https://sqlbits.com/)

For those interested in hearing about some of the new technologies coming from Microsoft, please feel free to register for one of those events.  I hope to see you there!

FYI – we just posted a white paper that covers some of the “how to think about Windows Azure SQL Database architecture” learning we have had while working with customers making transitions to the cloud from existing, on-premise SQL Server solutions.
