For messaging, Apache Kafka provide two mechanisms utilizing its APIs \u2013 <\/span><\/p>\n<ul class=\"ul1\" style=\"text-align: justify;\">\n<li class=\"li7\"><span class=\"s3\">Producer<\/span><\/li>\n<li class=\"li7\"><span class=\"s3\">Subscriber<\/span><\/li>\n<\/ul>\n<p class=\"p6\" style=\"text-align: justify;\"><span class=\"s1\">Using the Priority queue, it writes data to the producer.
