Abstract: A cache region can be created in a cache in response to receiving a cache region creation request from an application. A storage request from the application can identify the cache region and one or more objects to be stored in the cache region. Those objects can be stored in the cache region in response to receiving the storage request.

Abstract: Systems and methods that supply poll based notification system in a distributed cache, for tracking changes to cache items. Local caches on the client can employ the notification system to keep the local objects in sync with the backend cache service; and can further dynamically adjust the “scope” of notifications required based on the number and distribution of keys in the local cache. The server can maintain the changes in an efficient fashion (in blocks) and returns the changes to clients that perform the appropriate filtering. Notifications can be associated with a session and/or an application.

Abstract: A method is disclosed of logging transactions including the steps of storing log records for a plurality of transactions in one or more log files and linking each log record of each individual transaction of the plurality of transactions to any preceding log record of the same transaction so that all log records of each individual transaction are linked. In one embodiment, the method includes the step of maintaining a control record for at least each current transaction that specifies the most recent log record for the transaction to thereby provide a starting point for reserving the transaction if the transaction needs to be reserved.
