While this was previously effectively limited to 50, `DescribeAutoScalingGroups` now supports fetching 100 ASG per calls on all regions, matching what's documented: https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DescribeAutoScalingGroups.html ``` AutoScalingGroupNames.member.N The names of the Auto Scaling groups. By default, you can only specify up to 50 names. You can optionally increase this limit using the MaxRecords parameter. MaxRecords The maximum number of items to return with this call. The default value is 50 and the maximum value is 100. ``` Doubling this halves API calls on large clusters, which should help to prevent throttling.
Refactor to allow for optimisation
The pricing json for us-east-1 is currently 129MB. Currently fetching this into memory and parsing results in a large memory footprint on startup, and can lead to the autoscaler being OOMKilled. Change the ReadAll/Unmarshal logic to a stream decoder to significantly reduce the memory use.
