Does this plugin simulate the Lambda execution model?

[lrholmes]

I've noticed that my database is being 'connected' with every call to my function. My understanding from reading this AWS article is that any code outside of the specified handler functions, or the 'Execution Context', is maintained in anticipation of further invocations of the function.

Is the behaviour simulated at all in serverless-offline?

No, this isn't an exact simulation of the lambda environment. The concept of container reuse for example isn't applicable with serverless-offline; the code for your lambda is re-executed with every request.

If that's something you're looking for you could check out SAM Local: https://github.com/awslabs/aws-sam-local

Ah okay great - I was just looking for confirmation that there wasn't a flaw in my code causing the re-execution, as it would have caused problems in production, but is okay for development I think.

Thanks for your quick response!
