Kotlin vs the Cold Start: Winning Serverless on Hard Mode
The JVM is notoriously slow on serverless platforms, like AWS Lambda. You may just give up and switch to a dynamic language to avoid the bad cold starts. But you don't have to. Keep to Kotlin, understand the bottlenecks, and work around them.
None of the big names in the JVM ecosystem are designed to do this. Spring is too heavy, Jackson relies on reflection, and log4j is too complex. Come along for this journey where we rebuild a function; evaluating the improvements every step of the way. By the end, we'll have a high performing function rivalling even the fastest runtimes.
