Example 3 with StopReplicaTopicState

use of org.apache.kafka.common.message.StopReplicaRequestData.StopReplicaTopicState in project kafka by apache.

the class StopReplicaRequest method topicStates.

/**
 * Note that this method has allocation overhead per iterated element, so callers should copy the result into
 * another collection if they need to iterate more than once.
 *
 * Implementation note: we should strive to avoid allocation overhead per element, see
 * `UpdateMetadataRequest.partitionStates()` for the preferred approach. That's not possible in this case and
 * StopReplicaRequest should be relatively rare in comparison to other request types.
