At the recent re:Invent, AWS announced an update to its FaaS offering Lambda with SnapStart feature that reduces the cold start for Java Functions.

AWS unveils a new performance optimization feature called Lambda SnapStart, designed to improve startup times for latency-sensitive applications, and initially aimed at Java developers.

AWS Lambda SnapStart cuts Java startup times by initializing Java functions ahead of time and caching a snapshot of the initialized execution environment.

Consternation over Java's lambda syntax is the perfect example of how Java's evolution and incremental improvements have created a community of spoiled programmers.

Don't be intimidated by the prospect of doing functional programming in Java. This step-by-step example will help you learn basic Java lambda syntax quickly and effectively.
