Confluent 8.0 – KRaft Combined Mode Production Availability

I am upgrading Confluent from version 7.9.X to 8.0 by deprecating the ZooKeeper cluster and enabling KRaft mode in production. To reduce costs, we have decided not to add any additional nodes to the Kafka cluster to act as separate controllers. Instead, we plan to use the existing Kafka nodes in the cluster to serve both broker and controller roles (Combined mode). However, according to the documentation, the Combined mode is intended only for local experimentation and is not supported by Confluent in production. Could you please let us know when this Combined mode will be available for production use?

Here is the Confluent documentation link that mentions Combined mode is not supported in production:

hey @manjunathkmph

not sure whether this will every be supported.

for further reading/information:

Apache Kafka docs do not recommend combined mode for critical deployments either

[…]The key disadvantage is that the controller will be less isolated from the rest of the system. For example, it is not possible to roll or scale the controllers separately from the brokers in combined mode. Combined mode is not recommended in critical deployment environments.[…]

Thank you for replying. Probably i will put it on hold now.
