Abstract
One embodiment provides for a method to track replication state and providing quorum visible retrievals. The method includes assigning, by a writer node performing write operations, a sequence number. The sequence number is replicated with a write operation to other replica nodes in an asynchronous fashion thru a first network channel. On a second network channel, a state of a local system is communicated by sending a latest sequence number available that has been hardened to the other replica nodes. A query is obtained by a reader node, and a sequence number limit is selected. Results up to the sequence number limit are returned.
