Google Cloud Functions inherently support parallel processing. Each function invocation runs in its own isolated environment, allowing multiple invocations to run concurrently without interference. To enable this, you don’t need any specific configuration; it’s a built-in feature of the platform. However, you can control concurrency by setting the ‘max instances’ option during deployment. This limits the number of function instances that would be created for simultaneous executions. If not set, Google Cloud may choose to scale your function as needed.
