Abstract
Maintaining high availability of objects for both read and write transactions. Secondary copies of cached objects are created and maintained on disks of a secondary caching node and in remote data storage. In response to an update request, the secondary copies of cached objects are updated. Secondary cached objects are synchronously invalidated in response to the update request, and the update is asynchronously propagated to a secondary caching node.
