This module wraps Cloudformation due to lack of Data Pipeline support within Terraform itself. It creates the required IAM roles for EMR/Data Pipeline to backup a single DynamoDB table to S3 in a format which is restorable.
Things of note:
- EMR 6.1.0 is used not the latest version of 6.2.0, this is due to compatibility issues between Data Pipeline and EMR
- It does work with On Demand provisioning in which case the read_throughput_ratio variable can be ignored
- It is up to you to provide the Subnet, S3 bucket and SNS topic used to alerting
You must have the aws provider configuration with a region at the bare minimum e.g.
provider "aws" {
region = "us-east-1"
}
