One embodiment of a cache invalidation method includes storing an invalidation status usable by a computing node to identify, from a broadcast cache invalidation queue, a last processed invalidation that was processed with respect to an object cache used by the node. The method further comprises the node determining a set of unprocessed invalidations from the broadcast cache invalidation queue that are subsequent to the last processed invalidation determined from the invalidation status. The node processes the set of unprocessed invalidations to clear cached objects from the object cache. Based on processing the set of unprocessed invalidations to clear cached objects from the object cache, the invalidation status is updated with an identifier corresponding to a last invalidation from the set of previously unprocessed invalidations.

System and method for cache invalidation

System and method for broadcast cache invalidation

One embodiment includes a system comprising a repository configured to store objects, an object cache configured to cache objects retrieved from the repository by a node, a memory configured to store a broadcast cache invalidation queue accessible by a plurality of nodes and an invalidation status, a processor coupled to the memory and a computer readable medium storing computer-executable instructions. The computer-executable instructions can be executable to store cache invalidations in the invalidation queue, the cache invalidations identifying objects affected by operations, access the invalidation status to determine a last processed invalidation from the invalidation queue, determine a set of unprocessed invalidations from the cache invalidation queue, the unprocessed invalidations subsequent to the last processed invalidation, clear cached objects from the object cache based on the set of unprocessed invalidations and update the invalidation status based on a last invalidation from the set of unprocessed invalidations.
