Description
Accord requires replicas apply a consistent prefix of agreed operations, and permits many operations to be in-flight and depending on each other. These both benefit from strong liveness properties to ensure the system is always able to make rapid progress. To this end, we will introduce a gossip-like mechanism for communicating knowledge about the replication status of known transactions. Nodes will frequently reconcile their knowledge of each other’s knowledge with each other, so that the status of a transaction on other nodes can be rapidly determined.
