How to effectively monitor Exactly-once semantics in your data processing pipelines to ensure reliability and accuracy in event processing.
<?php // Example code for monitoring exactly-once semantics class EventProcessor { private $processedEvents = []; public function processEvent($eventId) { if (!$this->isEventProcessed($eventId)) { // Process the event $this->processedEvents[] = $eventId; echo "Processing event: $eventId\n"; // Additional processing logic... // Ensure to store in a reliable store to prevent reprocessing } else { echo "Event $eventId has already been processed.\n"; } } private function isEventProcessed($eventId) { return in_array($eventId, $this->processedEvents); } } $processor = new EventProcessor(); $processor->processEvent("event_1"); $processor->processEvent("event_1"); // This will be skipped ?>
