Abstract: A block-based storage system hosts logical volumes that are implemented via multiple replicas of volume data stored on multiple resource hosts in different failure domains. Also, the block-based storage service allows multiple client computing devices to attach to a same given logical volume at the same time. In order to prevent unnecessary failovers, a primary node storing a primary replica is configured with a health check application programmatic interface (API) and a secondary node storing a secondary replica determines whether or not to initiate a failover based on the health of the primary replica.

Abstract: Methods, systems, and computer-readable media for distributed transactions across multiple consensus groups are disclosed. A distributed transaction system comprises a proposer and a plurality of consensus groups, including a first consensus group comprising a first plurality of members and a second consensus group comprising a second plurality of members. The proposer proposes a transaction to at least a portion of the first consensus group and at least a portion of the second consensus group. A majority of the members in the first consensus group agree to perform the transaction, where the transaction is selected from a plurality of proposed transactions involving the first consensus group. A majority of the members in the second consensus group also agree to perform the transaction. The members of the first and second consensus groups perform the transaction to update a plurality of stored replicas.

Abstract: A block-based storage system hosts logical volumes that are implemented via multiple replicas of volume data stored on multiple resource hosts in different failure domains. Also, the block-based storage service allows multiple client computing devices to attach to a same given logical volume at the same time. A membership group authority authorizes sequence numbers for a given logical volume and an associated membership group. The members of the membership group ensure that the members are in agreement on the latest sequence number for the given logical volume before responding to read or write requests directed to the given logical volume.

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. In order to increase the speed of provisioning, a data replication may be provision with less than the total number of nodes to be included in the group. Once an initial set of nodes have been provisioned and are implementing a consensus protocol, the data replication group may begin to receive traffic. Furthermore, new nodes may be added to the group until the total number of nodes for the group has been reached.

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: 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. In order to increase the speed of provisioning, a pool of data replication groups may be maintained. When a request is received a data replication group may be selected from the pool, removed from the pool, and associated with the request. Furthermore, a replacement data replication group may be provisioned and added to the pool.
