Learn about the kafka-features CLI tool, which you can use to describe currently active features.

Describing currently active features

The kafka-features describe command returns the current features active in the cluster. The command returns a list of feature flags with their supported minimum and maximum versions as well as the finalized version, which is the version currently configured.
kafka-features --bootstrap-server [***HOST***]:[***PORT**] --command-config describe  
  • Replace [***HOST***]:[***PORT**] with the host and port of a broker.
  • Replace [***PROPERTY FILE***] with the location of a configuration file that contains all necessary security properties that are required to establish a connection with the Kafka service. This option is only required if your Kafka service is secured.
