terraform-aws-dynamodb-autoscaler

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

module "dynamodb_autoscaler" {
  source                       = "git::https://github.com/cloudposse/terraform-aws-dynamodb-autoscaler.git?ref=master"
  namespace                    = "eg"
  stage                        = "dev"

  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
