Great question! Let's break down these limits clearly for you:

• Batch Send (SendMessageBatch): The 10-message limit you found definitely applies here. AWS SQS enforces a hard cap of 10 messages per SendMessageBatch request for both standard and FIFO queues. If you need to send more than 10 messages, you'll have to split them into separate batch requests.

• Batch Receive (ReceiveMessage): This is where things differ slightly. The maximum number of messages you can pull in a single ReceiveMessage call is also 10—not the 200 you're aiming for. This limit applies to all queue types too.

To directly answer your second question: No, receiving 200 messages in one request isn't feasible. Instead, you'll need to make repeated calls to ReceiveMessage (each time setting MaxNumberOfMessages=10) until you've collected 200 messages or used up all available messages in the queue. Just remember that each call is subject to SQS's visibility timeout rules, so you'll want to handle that properly to avoid message duplication or processing delays.
