These alternate paths allow SQL Server to choose the best join option according to the number of rows returned on each execution. Adaptive JoinsĪdaptive Join is a query plan operator capable to create alternate paths inside the execution plan. We need to analyse each one of them to understand. We can choose always to recompile the plan or we can use the new Adaptive Query Processing features, but we can’t use both, they will be, at most, useless. This is in some ways the opposite of our traditional solution, the recompile options. Memory Grant Feedback and Adaptive Joins are part of the Adaptive Query Processing while Batch mode over row store is part of its big brother, Intelligent Query Processing.Īdaptive Query Processing is based on the idea of changing some behaviours of the query plan during the execution, without a new query compilation. That’s great! We can continue solving our problem with the recompile options but now these great new features will jump in and make our queries even better, right?
