Managing Kafka topics

Editing a Kafka topic

Log in to your Kubernetes cluster as a cluster administrator by setting your kubectl context.
Run the following command to initialize the Event Streams CLI on the cluster:
```
kubecl es init
```
Run the following command to edit the configuration of a topic:
```
kubectl es topic-update --name <topic-name> --config KEY[=VALUE]
```
For example:
- To update a topic called my-topic to have min.insync.replicas as 2:
```
kubectl es topic-update --name my-topic --config min.insync.replicas=2
```
- To update the number of topic partitions to 5 :
```
kubectl es topic-partitions-set -n my-topic -p 5
```
Note: To view all configuration options you can set for topics, use the help option as follows:
```
   kubectl es topic-update --help
```
