I am porting another site to Drupal. I am repurposing a script I used for a Drupal 5 import for a Drupal 6 import. After modifying it, I ran it for the first time and discovered the sequences table is gone. So then I looked at the node schema and noticed that nid is now auto_increment.

I'm assuming this means that the Drupal team is getting more serious about performance. Yes, that does mean a hit to portability, but I don't think many people are planning on running Drupal on Oracle any time soon. I'm pleased to see this development.

On that note, there is a free webinar "Achieving Optimal MySQL Performance For Drupal" Thursday. It looks interesting.
