in what sequence and how much times should be syncronized more than 3 replicas

Question

How much Sync sessions (in what PAIRS and in what SEQUENCE) should be done to say "EVERYTHING IS SYNCed"?

Let's say I have 3 replicas: A, B and C. So, for me, 3 sessions (A<->B, B<->C and A<->C) does the full syncing cycle.

And what if I have 5 or even more replica's. The optimal for me seems HUB scenario runned TWICE:

1. Let's take replica A as HUB;
2. Sync "A <-> B",  "A <-> C", "A <-> D" and finaly "A <-> E".
3. Repeat the step 2 (cause B doesn't have some new items from C, D and E, but A has everything,  and so on). "A <-> E" could be skipped, because E received all possible changes from the first cycle.

Am I right with such "HUB" scenario (4 + 3 sync sessions)? Or should i run EACH to EACH scenario (9 sessions) not to MISS SOMETHING?

Answer 1

assuming no changes has occurred between two syncs, a two-pass hub-spoke configuration should result to data convergence... that is assuming no conflicts occur as well...
