I've posted two blogs on testing methods of reducing page latch contention. I set up some tables for testing here (www.sqljared.com/blog/page-la...), then tested several approaches and provided results here (www.sqljared.com/blog/page-la...). #sqlfamily #sqlblog

#sqlfamily, consider upvoting this feedback to add a filter for an object id\name in Query Store. This will help make variant queries from Parameter Sensitive Plan Optimization more visible and allow us to see a procedure's activity in one view.

I've posted a new blog on PSPO at www.sqljared.com/blog/pspo-up.... This blog has links for a known issue, updates a previous script using sys.query_store_query_variant, and discusses PSPO plans with multiple variables. #sqlfamily #sqlblog
