As announced in September 2018, SQL Server 2019 expands the "adaptive query processing" features of SQL 2017 and relabels them as "intelligent query processing". This name now covers many features, such as batch mode on rowstore, memory grant feedback, interleaved execution, adaptive joins, deferred compilation, and approximate query processing.
In this high-paced session, we will look at all these features and cover some use cases where they might help - or hurt! - you.
