SQS does not trigger Lambda within 5 minutes in sequential-CodePudding

I'm new to AWS and working on SQS to trigger a lambda function. The order of the function is, Lambda A and pass queue to SQS, then SQS trigger Lambda B.

When I run Lambda A, I see Lambda B is triggered as I expected. However, when I run Lambda A within 5 minutes after the last run of Lambda A, Lambda B is not triggered. I'm wondering if there is a default time set of "5 minutes" to use SQS triggering Lambda function. If so, how can I change to "0 minute"?

Does anybody have the similar issue before? Thanks,

// Lambda A
// sends multiple messages to an Amazon SQS queue
module.exports.handler = async (event, context, callback) => {
  try {
    // sendQueue function is imported in the head of the file
    await sendQueue({ queueMessage }, QUEUE_URL)
  } catch (e) {
    console.error(e)
  }

  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Lambda A is done',
        input: event,
      },
      null,
      2
    ),
  }
}

// Lambda B
// After SQS receives queues from Lambda A, SQS triggers to invoke Lambda B
module.exports.handler = async (event, context, callback) => {
  // here calling Athena query with "await"
  return `Successfully processed a message.`;
}

In Lambda B, it gets a message content everytime the function receives a message from SQS like below.

[
  {
    messageId: 'b4146e42-a542-4e0e-bff9-ba7f96xxxxxx',
    receiptHandle: 'xxxxxxxxxxxxxxx',
    body: '{"queueMessage": "queueMessage sample text"}',
    attributes: {
      ApproximateReceiveCount: '1',
      SentTimestamp: '1643094105466',
      SequenceNumber: '18867376164708847616',
      MessageGroupId: '123',
      SenderId: 'xxxxxxxx:lambda-function-name',
      MessageDeduplicationId: 'xxxxxx',
      ApproximateFirstReceiveTimestamp: '1643094105466'
    },
    messageAttributes: { ReceiveMessageWaitTimeSeconds: [Object] },
    md5OfMessageAttributes: 'aaaaaaaa',
    md5OfBody: 'bbbbbbb',
    eventSource: 'aws:sqs',
    eventSourceARN: 'arn:aws:xxx.fifo',
    awsRegion: 'ap-northeast-1'
  }
]

Just ensure that you have not set the below setting in SQS. This setting could delay your Lambda function to running after x time.

After going over AWS documentation, I found the line below

If a message with a particular message deduplication ID is sent successfully, any messages sent with the same message deduplication ID are accepted successfully but aren't delivered during the 5-minute deduplication interval.

Basically, using FIFO queue of SQS, the messages sent during 5 minutes won't be delivered to avoid sending duplicate messages.
