Can a lambda function invoke itself?

This is an example of a function that will recursively call itself. Warning It’s possible to run into infinite loops with recursive calls.

What can trigger a lambda function?

Lambda Functions can be triggered in different ways: an HTTP request, a new document upload to S3, a scheduled Job, an AWS Kinesis data stream, or a notification from AWS Simple Notification Service (SNS).

What are the characteristics of lambda function?

The characteristics of lambda functions are: Lambda functions are syntactically restricted to return a single expression. You can use them as an anonymous function inside other functions. The lambda functions do not need a return statement, they always return a single expression.

Can Lambda be called recursively?

A recursive lambda expression is the process in which a function calls itself directly or indirectly is called recursion and the corresponding function is called a recursive function.

Can lambda function be called recursively?

You may not realise that you can write AWS Lambda functions in a recursive manner to perform long-running tasks. AWS Lambda limits the maximum execution time of a single invocation to 5 minutes.

Does EventBridge invoke Lambda asynchronously?

You can also configure Lambda to send an invocation record to another service. Lambda supports the following destinations for asynchronous invocation. AWS Lambda – A Lambda function. Amazon EventBridge – An EventBridge event bus.

Can Lambda have multiple triggers?

Your function can have multiple triggers. Each trigger acts as a client invoking your function independently. Each event that Lambda passes to your function has data from only one client or trigger.

How many triggers can a Lambda have?

How is lambda function different from normal function?

Regular Functions Lambda functions can only have one expression in their body. Regular functions can have multiple expressions and statements in their body. Lambdas do not have a name associated with them. That’s why they are also known as anonymous functions.
