Advanced AWS Lambda Interview Questions 1. How do you control access to Lambda functions? AWS Lambda uses IAM (Identity and Access Management) to control access at two levels: Resource-based policies specify which AWS accounts, services, and resources are allowed to invoke the function. The funct...
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 triggered, AWS Lambda service will call the Handler to execute the statements of the code....

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 part of Java 8 release. 1. What are … Java 8 Date Time API Java 8 contains the new Date and Time APIs/classes ...

Write your API logic in the function. For example, a simple “Hello World” endpoint: 1 2 3 4 5 6 exports.handler =async(event) => { return{ statusCode: 200, body: JSON.stringify({ message:"Hello, World!"}), }; }; 3.2 Step 2: Integrate API Gateway ...
We can now leverage the map function of datasets to iterate over the validation set of squad 2 and run prediction for each data point. Therefore we write a evaluate helper method which uses our pipelines and applies some transformation to work with the squad v2 metric....
For this to work, Accelerate provides a utility function that will synchronize the random number generators on each of the processes run during distributed training. By default, it only synchronizes the generator of your sampler, so your data augmentation will be different on each pr...
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...
