Ever wondered just how many CPU cores of KSQL Server you need to provision to handle your planned stream processing workload ? Or how many GBits of aggregate network bandwidth, spread across some number of processing threads, you’ll need to deal with combined peak throughput of multiple queries ? In this talk we’ll first explore the basic drivers of KSQL throughput and hardware requirements, building up to more advanced query plan analysis and capacity-planning techniques, and review some real-world testing results along the way.
