Add an SNS notification channel for increase / decrease throughput? about dynamodb-lambda-autoscale

[tmitchel2]

I think this is more analytics which i think should be separated out from the actual autoscaler itself. You might be able to set SNS notification based upon a cloudwatch trigger without changes to this.

Yeah that could work, but then I'd miss out / have to replicate logic from this to know why a decision was made to tune up / down from the autoscaler (as would anyone else using this project). I guess I could also subclass the ProvisionerConfigurableBase class but, then I'd have to maintain a fork

[tmitchel2]

Other people have mentioned the requirement of forking as a concern which i can understand and agree with, however i don't want this package to turn into a big blob. I think i will end up making it so you auto generate a template project, pull down this function using npm and then configure / add plugins to do additional work. That way users will be able to create and share additional features without polluting the 'small' core functionality. This will take a little time but it will definitely happen...

Ah that makes perfect sense, thanks for explaining the intentions. I will keep an eye out. If you get to the point where you have a solid arch. vision for some of this work and just need an extra set of hands, shoot me a message 😃

@awinder I'm having a similar requirement, to get the update notification in slack. Were you able to complete this.

[awinder]

Yeah I did, you can check out my fork if it's helpful https://github.com/awinder/dynamodb-lambda-autoscale/. I'm not actively maintaining anything with this though; we ended up going forward with dynamic-dynamodb instead which supported SNS messaging out of the box

This looks great. I will try your code and let you know. Thank you !!
