Matt Masson of the SSIS team has announced publicly that there are no new features for SSIS being released in SQL Server 2008 R2. Think that’s bad news? Think again – the team is hard at work on the next release (the term I’ll use for now) and based on some discussions I’ve been involved in, it sounds promising. SSIS is only going to get better and more competitive, so stay tuned!

There seems to be some misinformation going around about how SQL Server works with ordered data, especially with how the data is *physically* stored, even with a clustered-indexed table.

Please see this post for more details on SQL Server ordering: http://blogs.msdn.com/sqltips/archive/2005/07/20/441053.aspx

To add to that list a bit:

  • Updates are (almost) the same as select queries, internally, in that updates are turned into selects internally, which means the ordering rules of selects are also at play
  • Updates can have parallelism, meaning that updates do not have to preserve update order
  • Update order can’t be guaranteed because clustered indexes can be rebuilt with a different order
  • Ordering generally happens at the operator level within a query plan; not at the top
  • Unless you’ve seen it in BOL or in a MS Blog post, don’t assume anything with respect to SQL Server ordering – even if your queries operate on a given order today!

It would seem that the DATAllegro acquisition is complete as Microsoft has shipped its first technology preview of the project code-named “Madison” to ten customers for their feedback.

Madison looks to be quite the offering, allowing for rapid growth of a data warehouse architecture because of its “appliance” model as well as integration with existing SQL 2008 instances, minimizing time-to-market. Customers have reported loading over a terabyte of data within an hour using Madison and over 1.5 terabytes of query processing per minute.

When you have a chance, stroll on over to the Madison Web page to read more about it: http://www.microsoft.com/sqlserver/2008/en/us/madison.aspx

For those of you that wish to execute maintenance plans on a server and do not wish to have SSIS installed on said server, you will run into issues if you are on an RTM version of 2008 (version 10.0.1600).

The specific error message is “The SQL Server Execute Package Utility requires Integration Services to be installed by one of these editions of SQL Server 2008: Standard, Enterprise, Developer, or Evaluation. To install Integration Services, run SQL Server Setup and select Integration Services. The package execution failed. The step failed.”

This constraint has been lifted in Service Pack 1 and Cumulative Update 3, each. See: http://support.microsoft.com/kb/961126/
