Abstract: A method for automatically updating a plurality of brokers in a cluster of a distributed streaming platform within a container orchestration tool, the method including querying each of a plurality of brokers to obtain metadata from a distributed streaming platform; using the obtained metadata to identify a broker within the plurality of brokers that acts as a controlling broker; computing an order in which the plurality of brokers will be updated based on the obtained metadata, wherein the order specifies that the controlling broker will be updated last; and performing, via an update manager executed by at least one processor, a rolling update of each of the plurality of brokers according to the computed order.

Abstract: A virtualization platform provides fault tolerance for a primary virtual machine by continuously transmitting checkpoint information of the primary virtual machine to a collector process, such as a backup virtual machine. The virtualization platform includes virtual devices configured to keep track of state changes, for example, by using state flags or saving copies of prior state data. The virtualization platform generates incremental checkpoints by querying the virtual devices, which return state data based on whether the virtual devices have changed state since a prior checkpoint operation.
