Abstract:
A device comprises a non-transitory memory storage comprising instructions, a network interface, and one or more processors in communication with the memory storage and the network interface. The one or more processors execute the instructions to receive, via the network interface, a write request from a client device; send, via the network interface, the received write request to a set of follower devices; receive, via the network interface, a first acknowledgment from a majority of the follower devices of the set of follower devices that the write request was processed; send, via the network interface, the received write request to a set of peer devices; receive, via the network interface, second acknowledgments from a majority of the set of peer devices that the write request was processed; and send an acknowledgment of the write request to the client device in response to the receipt of the first acknowledgments and the second acknowledgments.
