摘要:
Systems and methods for replicating replicas in a sync community. Each replica in the sync community stores knowledge that represents changes the replica is aware of. Because each replica has its own knowledge, each replica does not need to know how many replicas are in the sync community or the topology of the sync community. By sending the knowledge with a request for changes, a replicating replica can enumerate the changes to replicate by comparing its knowledge with the received knowledge. After replication, the knowledge is updated. Knowledge may also include made-with-knowledge change IDs that permit each resolution to identify what a replica was aware of when a particular change was made. The made-with-knowledge values are used to detect conflicts during replication.
