Abstract: A scalable eventual consistency system. The system uses logical document journaling to provide eventual consistency across partitions in a large-scale service. The system allows for transactional edits to massively interconnected graphs of documents through parallelization without sacrificing linear scalability. The system separates the authority for edits from the replicated storage allowing efficient transactions and linear scalability. All document writes are written to document-specific partitions in a journal where they are queued until the changes are propagated to view-based partitions of a store. By continually checking the journal and attempting to replicate any pending document writes to the store, the system provides eventual consistency without complicated synchronization mechanisms.

Abstract: A replica management system facilitates maintaining a distributed and fault-tolerant state for a variable over an Information Centric Network (ICN) by replicating the variable across a set of ICN nodes. During operation, a variable-hosting ICN node can receive an Interest that includes a value-updating command for a replica instance of the variable, current values for a set of replicas of the variable, and a new value for the variable.

If so, the ICN node updates the local replica variable to the new value. However, if the current local value is not the authoritative value, the ICN node rolls back a state of the local replica variable to a previous state, and updates the local replica variable to the new value.

Abstract: Processes are disclosed for decreasing contention in caches in order to increase the efficiency of multi-threaded or multi-processor systems. By using multiple locks in a cache, smaller portions of the cache can be locked during cache updates (e.g., during a data update or a storage block eviction). As only small portions of the cache are locked at any given time, contention between threads, particularly in multi-processor implementations, will likely be reduced. For example, if different threads are trying to update different entries in the cache, the threads can proceed with updating the cache concurrently.
