Terraform Configuration Files

resource "aws_dms_endpoint" "s3_raw" {
  endpoint_id = "s3-raw"
  engine_name = "s3"
  endpoint_type = "target"
  extra_connection_attributes = "dataFormat=parquet;"
  s3_settings {
    service_access_role_arn = "${aws_iam_role.role.arn}"
    bucket_name = "${var.s3_bucket}"
    bucket_folder = "${var.raw_data_path}/dms"
    compression_type = "GZIP"
  }
}

Expected Behavior

The “extra connection status” in the DMS endpoint should be:

bucketFolder=data/raw/dms;bucketName=MY_BUCKET_NAME;compressionType=GZIP;csvDelimiter=,;csvRowDelimiter=\n;dataFormat=parquet;

Actual Behavior

The “extra connection status” in the DMS endpoint is:

bucketFolder=data/raw/dms;bucketName=MY_BUCKET_NAME;compressionType=GZIP;csvDelimiter=,;csvRowDelimiter=\n;

Notice the lack of dataFormat=parquet
