Thoughts on Parameter Sensitive Plan Optimization

Jared Poche shares some thoughts:

First, I wanted to point out that there are fixes to issues specific to Parameter Sensitive Plan Optimization in SQL Server 2022. The issue itself is documented at the link below.

When I heard about the issue, I heard that it could cause SQL Server 2022 to cause stack dumps every 15 minutes. The time interval made me think it was related to the default interval for Query Store, and that seems to be the case.

Jared has several thoughts on the topic as he puts together a talk on PSPO.
