1. A system for data center failover, comprising:
one or more processors configured to:
detect a failure of a first event processor associated with a first data center that includes a first main event store;
identify a second event processor associated with a second data center, the second event processor configured to process one or more events based on detecting the failure of the first event processor;
determine, based on a configuration associated with the first event processor or the second event processor, whether the second event processor is to process the one or more events from the first main event store; and
cause retrieval of the one or more events from the first main event store, for processing by the second event processor, based on determining the second event processor is to process the one or more events from the first main event store.
