为什么会提交重复的 AWS 作业

Question

每次文件上传到存储桶时，我的 S3 存储桶都会向 SQS 发送事件。 SQS 触发 lambda 函数，将作业提交到 AWS 作业队列。 每周，我的应用程序都会将超过 100K 个文件上传到 S3 存储桶。我预计每个上传的文件在 AWS 批处理队列中只有一个作业。但是我发现 Lambda 调用以及 Lambda 函数内的 SubmitJob api 调用受到限制。 我已将 Lambda 的并发数设置为 40。 我真正的问题是间歇性地为上传的文件提交超过 1 个作业。我无法弄清楚是什么导致 AWS 批处理队列中同一文件出现重复作业。

const Login = () => {

  const navigate = useNavigate();

  const validation = () => {

      setMessage("Password must be at least 6 characters");
      return false;
    }

    setMessage("");
    return true;
