High Performance Serverless Functions in Scala
This document discusses the use of high-performance serverless functions in Scala, specifically tailored for AWS Lambda. It highlights the benefits of compiling Scala code with GraalVM for improved startup times and memory efficiency, particularly for applications like Slack. The author provides a concise guide on packaging and deploying these Scala functions as native images to enhance performance in serverless environments.
