KafkaPartitionCount
- Description
- Partitions are the main concurrency mechanism in Kafka. A topic is divided into one or more partitions, enabling producer and consumer loads to be scaled. Specifically, a consumer group supports as many consumers as partitions for a topic.
- Default value
- 2
- Valid values
- Number of RCT instance * 2
Each RCT instance will have only two consumers per topic. This can be increased by increasing Kafka partitions from configuration and initiating multiple RCT instances.
For example: If you there are four Kafka partitions, then two RCT instances must be started. For six Kafka partitions there must be three RCT instances and so on. Each RCT instances must run on different nodes. If Kafka partitions are increased all the RCT instances must be restarted.
Replicafactor
- Description
- A replication factor is the number of copies of data over multiple brokers. The replication factor value should be greater than 1 always. This helps to store a replica of the data in another broker from where the user can access it.
- Default value
