 Here we have a bulk operation that sends two documents. Both are writing to the `id` field which is mapped as a `long` field type. The first document will be accepted, but the second document would cause a failure because the value `invalid_text` cannot be parsed as a `long`. This second document will be redirected to the failure store:
