This tool manages feature flags in Kafka.

positional arguments:
  {describe,upgrade,downgrade,disable,version-mapping,feature-dependencies}
    describe             Describes the current active feature flags.
    upgrade              Upgrade one or more feature flags.
    downgrade            Downgrade one or more feature flags.
    disable              Disable one or more feature  flags.  This  is  the same as downgrading
                         the version to zero.
    version-mapping      Look up the  corresponding  features  for  a  given  metadata version.
                         Using the command with no  --release-version  argument will return the
                         mapping for the latest stable metadata version
    feature-dependencies
                         Look up dependencies for a  given  feature  version. If the feature is
                         not known  or  the  version  not  yet  defined,  an  error  is thrown.
                         Multiple features can be specified.
