Abstract
Systems and methods are disclosed herein for providing fault tolerant processing of events. The system includes multiple consensus computers configured to communicate with one another and multiple event processors configured to process data such as events. Each consensus computer is further configured to receive a request to process a unit of data from an event processor. A consensus computer communicates with at least one other consensus computer to reach consensus as to whether the unit of data has previously been assigned to an event processor for processing. Then, a consensus computer sends a message to the event processor that sent the inquiry including instructions to either process the unit of data or not process the unit of data. Because the consensus computers determine whether a unit of data has previously been assigned to an event processor, the system ensures that an event is not processed more than once.
