[GitHub] [druid] asdf2014 opened a new issue #12007: Add a new field named `cluster` for multiple Druid clusters
asdf2014 opened a new issue #12007:
URL: https://github.com/apache/druid/issues/12007
### Description
For now, there are 5 fields in our Metric System, as follows:
- `timestamp` - the time the metric was created
- `metric` - the name of the metric
- `service` - the service name that emitted the metric
- `host` - the host name that emitted the metric
- `value` - some numeric value associated with the metric
However, they are not enough for multiple Druid clusters. We still need to add a new field named `cluster` in the Druid Metric System, so that we can use one single Kafka Topic to store all of metric data.
- `cluster` - the name of the Druid cluster, default as `druid`
Especially in the Cloud-Native situation, the creation of Druid cluster is very easy. If one single Kafka Topic is shared, not only the creation process of Kafka Topic can be omitted (for example, the Kafka cluster outside of Kubernetes), but the resource utilization rate will be relatively high (such as, the metrics data of some of Druid cluster is very tiny, even allocating a Partition is a bit of a waste of resource).

The [`druid.emitter.kafka.clusterName`](https://druid.apache.org/docs/latest/development/extensions-contrib/kafka-emitter.html) configuration is good enough, will close this one.
