    Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. The nodes of the data replication groups may generate logs containing information corresponding committed operations performed by the nodes. These logs may be collected and processed to obtain useful information corresponding to the operation of the data replication group. Furthermore, this processed information may be provided in the form of a stream to enable event driven operations corresponding to the logs.

    Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. During the execution of the set of nodes various nodes may become stale or otherwise obtain a state that is inconsistent with at least one other node of the data replication group. A catch up algorithm may be employed in which a set of teachers is initialized, the various node which may be stale may select a teacher from the set of teachers and perform learning operations. This process may be repeated until the state of the various nodes is current with at least one other node of the data replication group.

    Abstract: A computing system recovers volumes in a distributed computing environment while reducing downtime of storage servers. In an embodiment, a storage server contacts a control plane after a storage failure has occurred. If the storage server hosts an authoritative copy of an offline volume, the storage server is requested to restore the volume. Non-authoritative volumes are removed from the storage server and the storage server provides read access to the restored volume while resuming storage services.

    Abstract translation: 计算系统在分布式计算环境中恢复卷，同时减少存储服务器的停机时间。 在一个实施例中，存储服务器在发生存储故障之后接触控制平面。 如果存储服务器托管脱机卷的授权副本，则请求存储服务器还原卷。 非权威卷从存储服务器中删除，存储服务器在恢复存储服务时提供对已还原卷的读取访问。
