Learn how to include configuration and logging capabilities in an AWS Lambda, as well as libraries that reduce boilerplate code, while still keeping things lightweight
In this case, your WriteGetObjectResponse request returns the whole object to the requesting application in one call. Java Python Node.js package com.amazon.s3.objectlambda; import com.amazonaws.services.lambda.runtime.Context; import com.amazonaws.services.lambda.runtime.events.S3ObjectLambdaEvent...
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...
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 of java.util.List and the .asScala and .asJava converters. These are all necessary because the built-in Lambda serializer doesn’t understa...
This is not the case in the previous consumer example: the println() method is called on the System.out object, that is part of the method reference.The general syntax of a bound method reference is the following: expr:instanceMethod, where expr is an expression that returns an object, ...
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 ...
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 ...

creates an unnamed (lambda) function that can be easily passed as an argument to other function. After initializing the array, the snippet uses the <- operator to modify the sixth value in the array and then uses array slicing to create a new array containing the first six elements of the...
Python has an extensive Standard Library which is a collection of built-in modules, each providing specific functionality beyond what is included in the “core” part of Python. (For example, the math module provides additional mathematical functions. The random module provides the ability to...
