In the cluster mode, all topics have the same number of partitions. Set `"isSharding"` to `"true"` and assign the partitions to consume for the OAP server. Use commas to separate multiple partitions for the OAP server.
The Kafka Fetcher allows you to configure all the Kafka producers listed [here](http://kafka.apache.org/24/documentation.html#consumerconfigs) in property `kafkaConsumerConfig`. For example:
```yaml
kafka-fetcher:
selector: ${SW_KAFKA_FETCHER:default}
default:
bootstrapServers: ${SW_KAFKA_FETCHER_SERVERS:localhost:9092}
namespace: ${SW_NAMESPACE:""}
partitions: ${SW_KAFKA_FETCHER_PARTITIONS:3}
replicationFactor: ${SW_KAFKA_FETCHER_PARTITIONS_FACTOR:2}
isSharding: ${SW_KAFKA_FETCHER_IS_SHARDING:true}
consumePartitions: ${SW_KAFKA_FETCHER_CONSUME_PARTITIONS:1,3,5}
consumers: ${SW_KAFKA_FETCHER_CONSUMERS:1}
kafkaConsumerConfig:
enable.auto.commit: true
...
```
When using Kafka MirrorMaker 2.0 to replicate topics between Kafka clusters, you can set the source Kafka Cluster alias (mm2SourceAlias) and separator (mm2SourceSeparator) according to your Kafka MirrorMaker [config](https://github.com/apache/kafka/tree/trunk/connect/mirror#remote-topics).
```yaml
