SQS — Queues & Messages

SQS in Floci Studio has a full drill-down interface: create a queue, inspect its messages, send test payloads, and view all queue attributes — without leaving the browser.

Creating a queue

1. Click SQS in the sidebar.
2. Click Create Queue.
3. Enter a queue name (e.g., order-events).
4. Toggle FIFO Queue if you need ordered, exactly-once delivery. The .fifo suffix is added automatically.
5. Click Create.

The queue appears in the list immediately.

Sending a message

From the queue list, click Send on any queue row. A send panel opens inline.

Enter your message body (plain text or JSON) and click Send Message.

{
  "orderId": "4419",
  "customerId": "acme-corp",
  "total": 1250.00
}

For FIFO queues, a MessageGroupId of default is assigned automatically. You can override this in your SDK calls.

Reading messages (Messages tab)

Click a queue card (or click Inspect) to open the drill-down view. Switch to the Messages tab.

Click Receive Messages to poll the queue. Up to 10 messages are fetched (MaxNumberOfMessages=10, WaitTimeSeconds=0).

Each message shows:

• MessageId — unique identifier
• Body — expandable, with JSON pretty-print if valid JSON
• Sent timestamp and Receive Count
• ACK button — deletes the message (DeleteMessage) when you’re done with it

Caution

Messages received are not deleted automatically. Click ACK to remove them, or they’ll reappear after the visibility timeout.

Queue attributes

Switch to the Attributes tab to see:

Attribute	Description
ApproximateNumberOfMessages	Messages available to receive
ApproximateNumberOfMessagesNotVisible	Messages in flight (received but not deleted)
ApproximateNumberOfMessagesDelayed	Messages in delay period
VisibilityTimeout	Seconds a received message is hidden
MessageRetentionPeriod	How long messages are kept
QueueArn	Full ARN
RedrivePolicy	DLQ configuration

Purging a queue

Click Purge in the queue header (detail view) to delete all messages instantly. You’ll be asked to confirm.

SDK integration

import boto3

sqs = boto3.client("sqs", endpoint_url="http://localhost:4566",
                   region_name="us-east-1",
                   aws_access_key_id="test", aws_secret_access_key="test")

# Create
url = sqs.create_queue(QueueName="order-events")["QueueUrl"]

# Send
sqs.send_message(QueueUrl=url, MessageBody='{"orderId": "4419"}')

# Receive
msgs = sqs.receive_message(QueueUrl=url, MaxNumberOfMessages=5)["Messages"]
for msg in msgs:
    print(msg["Body"])
    sqs.delete_message(QueueUrl=url, ReceiptHandle=msg["ReceiptHandle"])
