The partitioning includes several major components of work (and can be linked below);
- partitioning large existing non-partitioned tables
- measuring performance impacts of partitioned aligned indexes
- measuring performance impacts of DML triggers for enforcing partitioned unique indexes

The SSIS Project Deployment Model is great! It really is the best thing since sliced bread! I specifically appreciate the package execution logging and reporting that is provided by this model but ….

Containers are one of the big things at the moment, Microsoft has recently announced that they will be bringing official support to Windows. While this is great news it is unlikely to be something most IT departments can use in the near term mainly because it takes time for everyone…
With my travel schedule, I don’t always get out to events where I can see a community speaker. Sometimes, I just see pros. That’s the case this month. Instead of skipping the month entirely, which feels wrong, I’ve decided to do a special award.
