摘要： Systems and methods are provided that enable a general framework for partitioning application-defined jobs (e.g., computation) in a scalable environment. The general framework decouples partitioning of a job from the other aspects of the job. As a result, the effort required to define the application-defined computation in a scalable environment is reduced or minimized, as the user is not required to provide a partitioning algorithm. The general framework further allows a user to provide load balancing conditions to allow for modification of how partitions are assigned.

摘要： Embodiments of the present invention relate to systems, methods and computer storage media for facilitating the structured storage of binary large objects (Blobs) to be accessed by an application program being executed by a computing device. Generally, the manipulation of Blobs in a structured storage system includes receiving a request for a Blob, which may be located by way of a Blob pointer. The Blob pointer allows for the data, such as properties, of the Blob to be identified and located. Expired properties are garbage collected as a manipulation of the Blob data within a structured storage system. In an embodiment, the Blob is identified by a key that is utilized within a primary structured index to located the requested Blob. In another embodiment, the requested Blob is located utilizing a secondary hash index. In an additional embodiment, the Blob is locate utilizing a file table.

摘要： Embodiments of the present invention relate to systems, methods, and computer storage media for geographically organizing the storage of data and hosted services in a distributed computing environment. An allocation constraint is utilized to identify and select a geo-region in which an affinity group that is comprised of a hosted service and/or data is to be physically stored. Additionally, a geo-domain within the geo-region is identified for hosting the hosted service and/or data of the affinity group. A stamp, such as a storage stamp or a computation stamp, is identified on the geo-domain for storing the hosted service and/or the data. The hosted service is stored in an identified computation stamp and the data is stored in an identified storage stamp. In an additional exemplary embodiment, the identification of a geo-domain involves analyzing resource information related to potential geo-domains within a geo-region.

摘要： Embodiments of the present invention relate to asynchronously replicating data in a distributed computing environment. To achieve asynchronous replication, data received at a primary data store may be annotated with information, such as an identifier of the data. The annotated data may then be communicated to a secondary data store, which may then write the data and annotated information to one or more logs for eventual replay and committal at the secondary data store. The primary data store may communicate an acknowledgment of success in committing the data at the primary data store as well as of success in writing the data to the secondary data store. Additional embodiments may include committing the data at the secondary data store in response to receiving an instruction that authorizes committal of data through a identifier.

摘要： Embodiments of the present invention relate to synchronously replicating data in a distributed computing environment. To achieve synchronous replication both an eventual consistency approach and a strong consistency approach are contemplated. Received data may be written to a log of a primary data store for eventual committal. The data may then be annotated with a record, such as a unique identifier, which facilitates the replay of the data at a secondary data store. Upon receiving an acknowledgment that the secondary data store has written the data to a log, the primary data store may commit the data and communicate an acknowledgment of success back to the client. In a strong consistency approach, the primary data store may wait to send an acknowledgement of success to the client until it receives an acknowledgment that the secondary has not only written, but also committed, the data.
摘要翻译：本发明的实施例涉及在分布式计算环境中同步复制数据。为了实现同步复制，可以考虑最终一致性方法和强一致性方法。收到的数据可能会写入主数据存储的日志，以便最终提交。然后可以用诸如唯一标识符的记录来注释数据，这有助于辅助数据存储器处的数据的重放。在收到辅助数据存储已经将数据写入日志的确认之后，主数据存储可以提交数据并将成功确认传回到客户端。在强一致性方法中，主数据存储可以等待向客户端发送成功确认，直到其接收到确认次要不仅写入但已经提交的数据。

摘要： A cloud computing platform contains a structured storage subsystem the provides scalable queues. The cloud computing platform monitors message throughput for the scalable queues and automatically increases or decreases subqueues that provide the operational functionality for each scalable queue. A visibility start time and cloud computing platform time are maintained for each message to provide an approximate first-in-first-out order for messages within each subqueue. A message in a subqueue may be available for processing when the current cloud computing time is greater than the visibility start of the message.

摘要： Embodiments of the present invention relate to systems, methods and computer storage media for erasure coding data in a distributed computing environment. A sealed extent is identified that is comprised of two or more data blocks and two or more index blocks. The sealed extent is optimized for erasure coding by grouping the two or more data blocks within the optimized sealed extent together and grouping the two or more index blocks within the optimized sealed extent together. The optimized extent may also be erasure coded, which includes creating data fragments and coding fragments. The data fragments and the coding fragments may also be stored in the distributed computing environment. Additional embodiments include monitoring statistical information to determine if replication, erasure coding or a hybrid storage plan should be utilized.

摘要： Systems, methods, and computer storage media for storing and retrieving data from a data store in a distributed computing environment are provided. An embodiment includes receiving data at a data store comprising a sequential journal store, RAM, and a non-sequential target store. When RAM utilization is below a threshold, received data is stored to the RAM as a write cache for the target store and the journal store. But, when the utilization is above the threshold, the data is stored to the journal store without write-caching to the RAM for the target store. When the RAM utilization falls below a threshold, data committed to the journal store, but not write-cached to the RAM for the target store, is later read from the journal store and write-cached to the RAM for a target store.
