[ovs-discuss] Regarding Clustered OVSDB

Hi,
It would be really helpful if you could address the below questions:


  1.  Is there a way for the client to know the leader ovsdb server IP in a clustered ovsdb model (other than from the logs)?
  2.  If an ovsdb-client is connected to a follower ovsdb server, are all the read/write operations forwarded to the leader by default? If not, is there a way for the leader to handle all reads, writes without clients knowing the leader IP.
  3.  In ovsdb monitoring, if the client does not receive a monitoring update (due to connectivity issues or if client is down), does the ovsdb-server keep track of that and send it later or is it lost?


Thanking you,

Regards,
Rutuja Madhure

Hi,

I had a few questions related to the clustered ovsdb model. It would be helpful if you could look at them.


  1.  Is there a way for the client to know the leader ovsdb server IP in a clustered ovsdb model (other than from the logs)?
  2.  If an ovsdb-client is connected to a follower ovsdb server, are all the read/write operations forwarded to the leader by default? If not, is there a way for the leader to handle all reads, writes without clients knowing the leader IP.
  3.  In ovsdb monitoring, if the client does not receive a monitoring update (due to connectivity issues or if client is down), does the ovsdb-server keep track of that and send it later or is it lost?


Thanking you,
