aws-lambda-java-events – This library provides predefined types that you can use when writing Lambda functions to process events published by Amazon S3, Kinesis, Amazon SNS, and Amazon Cognito. These classes help you process the event without having to write your own custom serialization logic.
Primitive Java types (such as String or int). Predefined AWS event types defined in the aws-lambda-java-events library.. For example S3Event is one of the POJOs predefined in the library that provides methods for you to easily read information from the incoming Amazon S3 event.. You can also write your own POJO class.
Lambda Functions in Java Today we are making Lambda even more useful by giving you the ability to write your Lambda functions in Java. We have had many requests for this and the team is thrilled to be able to respond. This is the first in a series of additional language options that we plan to make available to Lambda developers.
AWS Lambda is a serverless computing service provided by Amazon to reduce the configuration of servers, OS, Scalability, etc. AWS Lambda is capable of executing code on AWS Cloud. It runs in response to events on different AWS resources, which triggers AWS Lambda functions.
The AWS documentation on Lambda Java functions focuses on Lambda functions that are invoked in response to a defined AWS event. For example, a Lambda function could be invoked when an entry is made in a DynamoDB table or when a file is stored on AWS S3 storage.
AWS Lambda Deployment Package in Java. Your deployment package can be a .zip file or a standalone jar; it is your choice. You can use any build and packaging tool you are familiar with to create a deployment package.
Using aws-lambda-java-core. This package defines the Lambda Context object as well as interfaces that Lambda accepts.. Using aws-lambda-java-events. This package defines event sources that AWS Lambda natively accepts. See the documentation for more information.. Using aws-lambda-java-log4j2
When you create a Lambda function, you configure it in AWS Lambda, specifying things like the runtime environment (we’ll use Java 8 for this article), how much memory to allocate to it, identity and access management roles, and the method to execute.

Tutorial: How to Create, Upload, and Invoke an AWS Lambda Function This tutorial guides you through the process of a typical AWS Lambda workflow, and provides you with first-hand experience using Lambda with the AWS Toolkit for Eclipse.
AWS Lambda : Java : Kinesis Events. Ask Question 0. 1. java aws-lambda amazon-kinesis. share | improve this question. asked May 3 ’17 at 18:59. Meowts Meowts. 254 3 18. Your question is not specific. As general as your question is – the answer – it is the same regardless of the language run by the lambda. – johni May 3 ’17 at 20:40.
