Abstract: Shared resources can be isolated such that abuse of the resource by one user does not significantly affect the use of that resource by another user. A combination of access and flow control can be used, wherein a control gateway or other such component sits along a path between the user and the resource, such that the user obtains connections or access to the resource through the gateway. In this way, the gateway can control aspects such as the number of concurrent threads or channels granted to a user, as well as any delay in providing these threads or channels to the resource. A closed feedback loop can provide real-time information such that adjustments can be made dynamically, preventing abuse by users while also preventing the resource allocations from being underutilized.

Abstract: A first transaction manager of a partitioned storage group stores a first conditional commit record for a first write of a multi-partition transaction based on a first conflict detection operation. A second transaction manager stores a second conditional commit record for a second write of the transaction based on a second conflict detection operation. A client-side component of the storage group determines that both writes have been conditionally committed, and stores an unconditional commit record in a commit decision repository. A write applier examines the first conditional commit record and the unconditional commit record before propagating the first write to the first partition.

Abstract: The monitoring and recovery of data instances, data stores, and other such components in a data environment can be performed automatically using a separate control environment. A monitoring component of the control plane can include a set of event processors for monitoring a workload of the data environment, where an event processor detecting a problem in the data plane can cause a recovery workflow to be generated in order to recover from the detected problem. The event processors can communicate with each other such that if one of the event processors becomes unavailable, the other event processors in a set are able to automatically redistribute responsibility for the workload.

Abstract: Systems and methods for providing resource isolation in a shared computing environment using reinforcement learning (RL) techniques are disclosed. A resource isolation mechanism may be applied in a shared storage system, or database service, that limits the resource utilization of each namespace to its specified allocation. For example, the mechanism may be used to limit the I/O utilization of database applications in a shared computing system to a specified limit, and may apply RL techniques, along with domain-specific constraints, to the system to automatically control the rate of queries made by an application. RL techniques, such as those based on the State-Action-Reward-State-Action (SARSA) method, may be effective in controlling resource utilization for different workloads, and may be enhanced by their application in conjunction with domain-specific business rules.
