    // count and replication factor, or explicitly specified partition-to-replicas assignments.
    NewTopic createTopicRequest = replicasAssignments.isEmpty() ? new NewTopic(topicName, partitionsCount, replicationFactor).configs(nullableConfigs) : new NewTopic(topicName, replicasAssignments).configs(nullableConfigs);
