How to set SQS batch size to 1 in Terraform?

We're using an SQS in AWS to trigger a specific support Lambda that we have. Everything works or so, but in this case I'd like to make sure the batch size is 1 on the SQS.

I've read on this official terraform doc and cannot find anything about the batch size. I've also read this official AWS article on SQS tips but they do mention batch sizes, but not how to change them.

Is there any way to set the batch size to, let's say 1? I know this can have consequences in terms of execution time and cost, but in this particular case that does not matter for us.

Solution

  • It is set on the AWS Lambda event source mapping, the thing that connects SQS and Lambda:

    resource "aws_lambda_event_source_mapping" "example" {
  event_source_arn = aws_sqs_queue.sqs_queue_test.arn
  function_name    = aws_lambda_function.example.arn
  batch_size       = 1
}
