Abstract
Distributed computing system functionality is enhanced. Transmission of data changes may be incremental, thus reducing bandwidth usage and latency. Data changes may be propagated over geographic distances in an outward-only manner from a central data store to one or more servers or other remote nodes, using proactive updates as opposed to making cache updates only in reaction to cache misses. Cache expiration and eviction may be reduced or avoided as mechanisms for determining when cached data is modified. A central computing environment may proactively push incremental data entity changes to place them in remote data stores. Remote nodes proactively check their remote data store, find changes, pull respective selected changes into their remote node caches, and provide current data in response to service requests. Data may be owned by particular tenants. Data pulls may be limited to data in selected categories, data of recently active tenants, or both.
