Kafka Implementation:

`class KafkaProducerSingleton:
_instance = None
_lock = threading.Lock()

@classmethod
def get_instance(cls, *args, **kwargs):
    if cls._instance is None:
        with cls._lock:
            if cls._instance is None:
                cls._instance = KafkaProducer(
                    bootstrap_servers=settings.KAFKA_TRACES_CLUSTER,
                    api_version=(0, 10),
                    retries=100,
                    max_block_ms=5000
                )
    return cls._instance`
