We have been using AWS Stacksets to deploy directly from AWS UI(Cloudformation) and would like to use Terraform to deploy the same Stacksets templates.
Based on documentation it appears we should be able to supply multiple regions but i dont see an option to supply multiple regions for parallel execution. However, per document (link below) for Resource: aws_cloudformation_stack_set it has a operational_preference parameter that allows PARALLEL execution.
region_concurrency_type- (Optional) The concurrency type of deploying StackSets operations in Regions, could be in parallel or one Region at a time.
Please advise if there is a way around to provide multiple regions for resource aws_cloudformation_stack_set or another resource that allows such.
