--------------------------------------------------
Summary: Liveness / Repair
Key: CASSANDRA-17096
URL: https://issues.apache.org/jira/browse/CASSANDRA-17096
Project: Cassandra
Issue Type: Sub-task
Reporter: Benedict Elliott Smith
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.
