Intermediate AWS Lambda Interview Questions 1. How can we deploy dependencies alongside Lambda code? There are a few options for packaging dependencies with Lambda code: Direct inclusion: For interpreted languages, we can put dependency files along with our function code in the .zip deployment packag...
Learn about Java Lambda Expressions in Functional Programming. Understand the syntax, use cases, and benefits of using lambdas in Java.
AWS Lambda is one of the most popular serverless platforms. It supports Java through the AWS SDK for Java, allowing developers to write functions in Java 8, 11, or 17. Example: Creating a Simple AWS Lambda Function in Java Set up the AWS SDK: Add the AWS Lambda dependencies to y...
One of the drawbacks of serverless architecture is cold starts, where a function takes longer to execute if it hasn’t been used recently. However, AWS has made significant improvements to mitigate this issue in 2025. 5.2 Vendor Lock-In Using AWS Lambda ties your application to the AWS ec...
Lambda Expressions in Java Lambda expressions are known to many of us who have worked on advanced languages like Scala. The term “lambda” has its origin in Lambda calculus that uses the Greek letter lambda (λ) to denote a function abstraction. Lambda expressions were introduced to Java as ...
Java C# Go Python The core concepts of writing the lambda code is as follows. Handler: Handler is the function which AWS Lambda calls when it is triggered by the cloud events. The first step in writing the Lambda functions is to define the Handler function. When the Lambda functions are ...
js += "var a = map.call(names, function(name) { returnJava.type("LambdaTest”).wrap(name.length()) })"; Here’s wrap – 1 2 3 4 publicstaticintwrap(String s) { returns.length(); } Now let’s play a game. How many frames will be in that stack? Think about it for a...
aws lambda create-function --function-name FindAllMovies \ --zip-file fileb://deployment.zip \ --runtime go1.x --handler main \ --role arn:aws:iam::ACCOUNT_ID:role/FindAllMoviesRole \ --region us-east-1 Once function is created it will give us the output same as shown in a sc...
The workaround I found was to use the map function as the success case and the orElseGet to return the failure case. In both branches the code returns an instance of ThrowingRunnable by having a lambda return a lambda. Therun()is then called at the end and it can throw any exception...
