Abstract
Embodiments of the present invention relate to systems, methods, and computer storage media for replicating data in a distributed computing environment utilizing a combination of replication methodologies. A full-object replication may be utilized to replicate a full state of an object from a primary data store to a secondary data store. A checkpoint created after initiating the full-object replication may be parsed to identify changes to the object that have been entered since initiating the full-object replication. This replication process is referred to as a delta-checkpoint replication methodology. Additionally, in an embodiment, a log-based replication methodology may be utilized. The log-based replication may communicate data from a log of the primary data store to the secondary data store. It is also contemplated in an exemplary embodiment that when the log-based replication fails to maintain a throughput threshold, one of the other replication methodologies may be initiated, at least temporarily.
