摘要： Embodiments of the present invention relate to invoking and managing a failover of a storage account between partitions within a distributed computing environment, where each partition represents a key range of data for the storage account. The partitions affected by the failover include source partitions hosted on a primary storage stamp and destination partitions hosted on a secondary storage stamp, where the storage account's data is being actively replicated from the primary to the secondary storage stamp. Upon receiving a manual or automatic indication to perform the failover, configuring the source partitions to independently perform flush-send operations (e.g., distributing pending messages as a group) and then configuring the destination partitions to independently perform flush-replay operations (e.g., aggressively replaying currently pending transactions). Upon completing the flush-replay operations, designating the secondary storage stamp as a new primary storage stamp such that live traffic is directed to the new primary storage stamp.

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： Embodiments of the present invention relate to invoking and managing migration operations 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 migration operations 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 equipped to replicate the storage account's data therebetween upon initiating a migration. Upon substantial completion of a bootstrapping phase of replication, one migration operation includes designating the secondary storage stamp as a new primary storage stamp such that the destination partitions commence processing client requests, sending resultant transactions to the source partitions, and providing read and write access thereto. Another migration operation includes designating the primary storage stamp as a new secondary storage stamp such that the source partitions commence replaying the transactions.
