It’s finally ready!
For the last two years, I’ve been working on-and-off on a new community resource. It was postponed during 2015 while I mentored 50+ people, but this year I’ve had a bunch of time to work on it.
I present to the community a comprehensive library of all wait types and latch classes that have existed since SQL Server 2005 (yes, it includes 2016 waits and latches).
The idea is that over time, this website will have the following information about all wait types and latch classes:
- What they mean
- When they were added
- How they map into Extended Events (complete for all entries already)
- Troubleshooting information
- Example call stacks of where they occur inside SQL Server
- Email link for feedback and questions
As of today, I have complete information for more than 150 common wait types (897 entries in the library) and 24 common latch classes (185 entries in the library), and I’m adding more information constantly.
If there’s one that I haven’t done yet, and you’re really interested in it, click the email link on the page to let me know. Also, if you’ve seen something be a bottleneck that I haven’t, let me know so I can update the relevant page too.
I’m doing this because there is so little information about waits and latches available online and I know that people are constantly searching for information about them. This is very much a labor of love for me as wait statistics are now my favorite area to teach.
Waiting until it’s complete isn’t feasible, so it’s open and available for use now!
