The UPTODATE_CURSOR_V2 structure defines a concrete type for the replication state relative to a given DC.

 typedef struct {
   UUID uuidDsa;
   USN usnHighPropUpdate;
   DSTIME timeLastSyncSuccess;

uuidDsa: The invocationId of the DC performing the update.

usnHighPropUpdate: The USN of the update on the updating DC.

timeLastSyncSuccess: The time at which the last successful replication occurred from the DC identified by uuidDsa; for replication latency reporting only.

A cursor c with c.uuidDsa = x and c.usnHighPropUpdate = y indicates a replication state that includes all changes originated by DC x at USN less than or equal to y.
