How to make AWS Lambda stop execution?

Question

I have an AWS Lambda function does operations against Kinesis Firehose. The function uses backoff mechanism. (which at this time I think wasting my computation time).

But anyway, in some point in my code, I would like to fail the execution. What command should I use in order to make the execution stop?

P.s. I found out that there are commands such as:

• context.done()
• context.succeed()
• context.fail()

I've got to tell you, I could not find any documentation about these commands in AWS documentation.

Those methods are available only for backward compatibility, since they were first introduced with Node.js v0.10.42. If you use NodeJS version 4.* or 6.*. Use the callback() function.

Check: Using the Callback Parameter in Lambda for more information how to take advantage of this function.
