gcloud managed-kafka topics update mytopic --cluster=mycluster --location=us-central1 --partitions=3

POSITIONAL ARGUMENTS

Topic resource - Identifies the topic to be updated. The arguments in this group can be used to specify the attributes of this resource. (NOTE) Some attributes are not given arguments in this group but can be set in other ways.

provide the argument --project on the command line;
set the property core/project.

This must be specified.

TOPIC

This positional argument must be specified if any of the other arguments in this group are specified.

REQUIRED FLAGS

At least one of these must be specified: --partitions=PARTITIONS The number of partitions in a topic. You can increase the partition count for a topic, but you cannot decrease it. Increasing partitions for a topic that uses a key might change how messages are distributed. At most one of these can be specified: --clear-configs Remove all the configurations for the topic. --configs=[KEY=VALUE,…] Configuration for the topic that are overridden from the cluster defaults. The key of the map is a Kafka topic property name, for example: cleanup.policy=compact,compression.type=producer. If you provide a map with a key that already exists, only that configuration is updated. If the map contains a key that does not exist, the entry is appended to the topic configuration.
