Mida teha, kui sõnumeid ei toimetatud RabbitMQ-sse pärast tehingu lõpetamist?

If messages were not delivered to RabbitMQ after the transaction is completed, the following steps are necessary:

1. Verify that the transaction was indeed committed. If the transaction was rolled back, messages will not be sent.
2. Use publisher confirms in RabbitMQ to ensure that the broker has received and stored the message.
3. Implement a mechanism for resending messages in case of delivery failure.
4. Log errors and delivery events for later analysis.

Example of using publisher confirms in PHP with the php-amqplib library:

$channel->confirm_select();
$channel->basic_publish($msg, '', 'queue_name');

if (!$channel->wait_for_pending_acks_returns()) {
    // Handle delivery error
    // You can retry sending or save the message for a later attempt
}

This ensures reliable message delivery even in case of failures.
