Ingesting from Kafka 8
----------------------
The previous examples are for Kafka 7. To support Kafka 8, a couple changes need to be made:
- Update realtime node's configs for Kafka 8 extensions
- e.g.
- `druid.extensions.coordinates=[...,"io.druid.extensions:druid-kafka-seven:0.6.160",...]`
- becomes
- `druid.extensions.coordinates=[...,"io.druid.extensions:druid-kafka-eight:0.6.160",...]`
- Update realtime task config for changed keys
- `firehose.type`, `plumber.rejectionPolicyFactory`, and all of `firehose.consumerProps` changes.
