Python: S3BackendConfig - CDK Terrain (CDKTN)

Stores the state as a given key in a given bucket on Amazon S3. This backend also supports state locking and consistency checking via Dynamo DB, which can be enabled by setting the dynamodb_table field to an existing DynamoDB table name. A single DynamoDB table can be used to lock multiple remote state files. Terraform generates key names that include the values of the bucket and key variables. Warning! It is highly recommended that you enable Bucket Versioning on the S3 bucket to allow for state recovery in the case of accidental deletions and human error. Read more about this backend in the Terraform docs: https://developer.hashicorp.com/terraform/language/settings/backends/s3
