Master-Master seems easy, but needs proper care. For example:
- have you taken care of auto increment values? What if there's
concurrent insert of different acct record to both sql node, will they
have the same radacctid?
- what happens when an acct-start got to node 1, but before the change
was replicated, an acct-stop for the same session got to node 2? Can
your sql query/replication setup handle that?
