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: 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: Generally described, one or more aspects of the present application correspond to techniques for dynamically determining token bucket sizes for different types of transactions occurring at a node in a distributed consensus-based transaction system. For example, each node can store a number of cells, with such cells being replicated across a number of nodes. Each cell can assume various roles in consensus transactions, for example being a leader or simple juror, or being unsure of its leader's identity and requesting leadership. Each node can determine the overall number of transaction tokens that it will assign during a given time period based on the cell composition, and can allocate those tokens to a leader election token bucket and a customer traffic token bucket based on the cell composition.
