AWS Lambda provides convenient to use functions service, which allows running code without presetting or administering the server and which enables calling functions directly from any Web or mobile application to get expected result. We can read business data, perform complex computations and output the...

All helper functions follow standard Java naming convention. They are either Library methods or Directives. FluentJPA.SQL() This is an "entry-point" method to the FluentJPA. It accepts a Java lambda and translates it to SQL query. There are few conventions: Lambda parameters must be entity ...
Writing Lambda functions in Scala requires dealing with some “Javaisms” at the points of entry and exit. You can notice this in code above: the use ofjava.util.Listand the.asScalaand.asJavaconverters. These are all necessary because the built-in Lambda serializer doesn’t understand native...
The main ones that Python programs can use are side-effect-free functions, higher-order functions, and lambda functions.Side EffectsSide effects are any changes a function makes to the parts of the program that exist outside of its own code and local variables. To illustrate this, let’s ...

Lambda functions may retry unintentionally. Therefore, each Lambda function should be idempotent. Once again, lucky for us, our APIs are built to handle this. For example, our Response Import API allows the user to pass an idempotency key to prevent importing identical responses in the case of...

Well, the lambda function is the functionality behind a given service. Allowing the infrastructure and functionality to work in harmony in isolated repositories / components, which can be injected into any AWS project is what makes this framework so powerful....
