A system facilitating scaling of topics is provided. During operation, the system can suspend a stateful application of a topic and a stateful backup topic on an event-driven platform. The topic corresponds to a stream of events associated with the application. The system can modify configuration at the platform to allow a new set of partitions of the topic and a new set of backup partitions of the backup topic. The system can identify a state of event records from the application in a previous backup partition and identify a new backup partition allocated to the application. If they are different, the system can transfer the state to the new backup partition. The system can resume the application for generating an updated state, which is maintained at the new backup partition, based on the state and subsequent event records associated with the application.
