摘要： A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents. Volumes facilitate control of data placement, creation of snapshots and mirrors, and retention of a variety of control and policy information. Also addressed is the use of distributed transactions in a map-reduce system; the use of local and distributed snapshots; replication, including techniques for reconciling the divergence of replicated data after a crash; and mirroring.

摘要： A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. A primitive storage layer (storage pools) knits together raw block stores and provides a storage mechanism for containers and transaction logs. Storage pools are manipulated by individual file servers. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents. Volumes facilitate control of data placement, creation of snapshots and mirrors, and retention of a variety of control and policy information. Key-value stores relate keys to data for such purposes as directories, container location maps, and offset maps in compressed files.

摘要： Embodiments of the present invention relate to a method and mechanism for managing location information in a wireless portal environment. The method consists of acquiring the location information from a user's location-enabled wireless device which is in communication with a wireless network, storing the location information in a storage device in the wireless network, retrieving the location information from the storage device in the wireless network, and disseminating the location information to a client which is also in communication with the wireless network. A client can be any type of network presence that is enabled to provide services that are enhanced with knowledge of a user's physical location in a wireless portal environment. The location information can be geophysical information derived from global positioning system (GPS) or any other location-specific information from a suitable source.
