Abstract
Systems and methods for adaptive asynchronous data replication in a data storage system are described herein. The data storage system includes a plurality of zones each having a plurality of storage nodes, each having a plurality of storage devices. The system provides for replication according to policies associated with data items such that data items are stored among a plurality of zones. The data items are stored as one or more objects and may be replicated asynchronously or synchronously. The system adapts the synchronicity of the replication based on a combination of criteria including a put performance threshold, a backlog threshold, latency and the current synchronicity status. By automatically adjusting the replication synchronicity, the system and methods achieve improved performance while maintaining data resiliency.
