A Data Synchronization and Failover Management (DSFM) system monitors simultaneous execution of non-identical instances of a software application and may label as a particular result of the software application the earliest output corresponding to that result produced by one of the instances. The DSFM may label one of the instances as a primary instance and the other instances as secondary instances and, if the primary instance fails, may re-label one of the secondary instances that computed all of the operations associated with the last result produced prior to the failure of the primary instance, as a new primary instance.

Systems and methods for data synchronization and failover management

Embodiments of the present invention may provide an improved distributed computing system. Entities in the distributed computing system may be divided into four categories: writers, readers, gateways, and applications. End users may interact with the system via the applications through the gateways. The role of writers and readers may be separated to distribute computational burdens. Writers may generate messages for an event stream. The messages may include a timestamp for consistent global ordering. The readers may arrange messages from various writers based on the timestamps to generate globally time-consistent event streams.

System and method for creating time-accurate event streams

Embodiments of the Message Retransmission Mechanism Apparatuses, Methods and Systems ('MRM') transform application requests for message journals via MRM components into expedited access to segmented message streams. In one implementation, the MRM may obtain message journal of messages written by applications during system operations and divide up the message obtained from the complete message journal into message segments. In some implementations, the MRM may provide recovering applications access to said message segments for expedited message consumption.
