Hash join was introduced in MySQL 8.0.18 and was presented for the first time at FOSDEM 2020. Since then, the performance of hash join has been improved, and I will present results that show this. We will also discuss what kind of queries benefit from hash join, what you need to do for hash join to be used, and how to tune your system for optimal hash join performance.
