AWS Lambda asynchronous invocation using Zappa

An AWS Lambda function is nothing but a function deployed at an AWS Lambda container. Hence, executing it is just a matter of invoking a function. There are various methods of invocation provided by AWS. How you go about integrating and configuring the invocation to achieve asynchronous execution is entirely up to you. We have seen in the previous section how to go about asynchronous execution using the Boto3 SDK. Now, we are going to explore the various ways of invocation that are provided by Zappa.

 

Asynchronous AWS Lambda invocation using the task decorator

Zappa provides a super-easy way to configure your Lambda execution in asynchronous mode. Zappa has an implementation of asynchronous execution using a decorator method called zappa.async.task. This decorator can be used with any function we want to execute in asynchronous mode. The following is an example from Zappa's official GitHub page (https://github.com/Miserlou/Zappa#asynchronous-task...
