Devices within a distributed computing environment must typically exchange large amounts of configuration data in order to identify and access various distributed resources. For example, a central server within a client-server computing model may be required to distribute a large amount of configuration data to each client within its distributed computing environment in order to enable these clients to identify and access the distributed resources they require to perform various tasks. Similarly, a peer within a peer-to-peer computing model may request a large amount of configuration data from one or more of its peers in order to identify and access the distributed resources the peer requires to perform various tasks.
A distributed computing system's configuration data is typically represented in the form of a tree that identifies the hierarchical relationship of each object within the distributed computing system. Nodes within this tree may represent objects (such as a cluster, system, group, application, resource, or attribute of the same) within the distributed computing system connected in parent-child relationships. Devices within the distributed computing system may be interested in either the entire tree (e.g., peers within a peer-to-peer model or a server within a client-server model may be interested in the entire tree) or a subset of the tree (e.g., clients within a client-server model may only be interested in a subset of the tree).
Unfortunately, due to the typical size of this configuration data, an inordinate amount of network bandwidth may be required to exchange even a subset of this configuration data among devices within the distributed computing system, resulting in potential delays. For example, the amount of time required for a client to recover from a failure may be dramatically increased due to the time required to request, receive, and process a snapshot of (even a subset of) a central server's configuration data. As such, the instant disclosure identifies a need for systems and methods for efficiently synchronizing configuration data within distributed computing systems.
