摘要: Version indicators within an existing range can be associated with a data partition in a distributed data store. A partition reconfiguration can be associated with one of multiple partitions in the data store, and a new version indicator that is outside the existing range can be assigned to the reconfigured partition. Additionally, a broadcast message can be sent to multiple nodes, which can include storage nodes and/or client nodes that are configured to communicate with storage nodes to access data in a distributed data store. The broadcast message can include updated location information for data in the data store. In addition, a response message can be sent to a requesting node of the multiple nodes in response to receiving from that node a message that requests updated location information for the data. The response message can include the requested updated location information.

摘要: 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.
