ScaleUp to the number of message left in queue if < maxSize / 10

[vincentsarago]

I'd like to know if we could change the behavior of the scaleUp lambda function to integrate the number of message left in the queue as a variable.

Let's consider that I have a stack with a maxSize set to 500, if a queue has 3 messages the stack will scale up to 50 when I need only 3 watcher.

How to ?

modify

ecs-watchbot/lib/template.js

Lines 778 to 780 in 01a777b

	exports.handler = function(event,context){
	const result = Math.round(Math.max(Math.min(parseInt(event.ResourceProperties.maxSize) / 10, 100), 1));
	response.send(event, context, response.SUCCESS, { ScalingAdjustment: result });

to first get the number of message left in the queue, and then choose the min between nMessage, maxSize/10 and 100.
