Terraform module to provision DynamoDB autoscaler.
Autoscaler scales up/down the provisioned OPS for a DynamoDB table based on the load.
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!
Usage
IMPORTANT: The master
branch is used in source
just as an example. In your code, do not pin to master
because there may be breaking changes between releases.
Instead pin to the release tag (e.g. ?ref=tags/x.y.z
) of one of our latest releases.
module "dynamodb_autoscaler" {
source = "git::https://github.com/cloudposse/terraform-aws-dynamodb-autoscaler.git?ref=master"
namespace = "eg"
stage = "dev"
name = "cluster"
dynamodb_table_name = "eg-dev-cluster-terraform-state-lock"
dynamodb_indexes = ["first-index", "second-index"]
dynamodb_table_arn = "arn:aws:dynamodb:us-east-1:123456789012:table/eg-dev-cluster-terraform-state-lock"
autoscale_write_target = 50
autoscale_read_target = 50
autoscale_min_read_capacity = 5
autoscale_max_read_capacity = 20
autoscale_min_write_capacity = 5
autoscale_max_write_capacity = 20
}
