Brent Ozar reviews a Microsoft Research paper:
In the Microsoft Research paper Plan Stitch: Harnessing the Best of Many Plans by Bailu Ding, Sudipto Das, Wentao Wu, Surajit Chaudhuri, and Vivek Narasayya (2018), the authors propose something really cool: watching an execution plan change over time, splitting it into parts, and then combining parts to form a SuperPlan™. (They don’t call it a SuperPlan™ – it just seems appropriate, right?)
That looks like an interesting paper, and Brent has a few more if you agree.
