| removed completely in Druid 0.16.0. Operationally, realtime nodes were difficult to configure, deploy, and scale because |
| each node required an unique configuration. The design of the stream pull ingestion system for realtime nodes also |
| suffered from limitations which made it not possible to achieve exactly once ingestion.</p><p>The extensions <code>druid-kafka-eight</code>, <code>druid-kafka-eight-simpleConsumer</code>, <code>druid-rabbitmq</code>, and <code>druid-rocketmq</code> were also |
| removed at this time, since they were built to operate on the realtime nodes.</p><p>Please consider using the <a href="/docs/latest/development/extensions-core/kafka-ingestion">Kafka Indexing Service</a> or |
