Client knows if it's connected to a leader or not by monitoring the _Server database, so it may decide to re-connect to a different server if leader-only connection is required. It's expected that in most cases client knows IPs of all the database servers in a cluster. > 2.

Write transactions are forwarded to a leader. Please, read the documentation. It covers this and a lot more: https://docs.openvswitch.org/en/latest/ref/ovsdb.7/#understanding-cluster-consistency > 3.

Connection is either unix socket, or TCP, or SSL. They all guarantee data delivery. If connection is dropped for any reason, client will have to establish a new connection and send a new monitor request. > > > Thanking you, > > Regards, > Rutuja Madhure _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
