    摘要： Embodiments of the present invention relate to invoking and managing load-balancing operation(s) applied to partitions within a distributed computing environment, where each partition represents a key range of data for a storage account. The partitions affected by the load-balancing operation(s) are source partitions hosted on a primary storage stamp and/or destination partitions hosted on a secondary storage stamp, where the primary and secondary storage stamps are located in geographically distinct areas and are equipped to replicate the storage account's data therebetween. The load-balancing operation(s) include splitting partitions into child partitions upon detecting an increased workload as a result of active replication, merging partitions to form parent partitions upon detecting a reduction in workload as a result of decreased processing-related resource consumption, or offloading partitions based on resource consumption. A service within a partition layer of the storage stamps is responsible for determining when to invoke these load-balancing operation(s).

    摘要： Presented herein are methods of continuously verifying data and repairing errors introduced during replication. In a particular embodiment, a primary data store sends out information sufficient to create a checkpoint together with a checksum for the data being verified at that checkpoint. At the secondary data store, a checkpoint is created in accordance with the checkpointing information, and a checksum is calculated over the indicated data at the created checkpoint. If the calculated checksum disagrees with the received checksum, additional checksums are calculated over subranges of the indicated data and compared with corresponding checksums over the data at the primary data store. The checksums at the primary data store may be requested from the primary data store or calculated locally based on the received overall checksum. Once an erroneous entry is identified, it can then be re-replicated from the primary data store to restore data consistency.

    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.
