[Bucardo-general] Helping to understand delta update

Hi!

I have been evaluating Bucardo and so far it looks great, thanks!

Case which I have here has n nodes, and one "main" database, but all nodes should act as a master.

First I thought I could implement this running one centralized bucardo instance, but as those nodes are sometimes offline, it seems that bucardo will stop syncing if node is down.

So, now i have bucardo running on every node, and those always have dbgroup, having local database and main database and then sync with makedelta=1.

Now, when I update data on node A, it updates right away to main.

Also, when up update data on main, it updates right away from main to node A and node B.

But, making change to node A only gets to node B when:

  *
bucardo is restarted
  *
there is some other change on main

So my question is that is there some polling interval or so, which controls the delta updates?
