OVSDB clustering needs from mdsal


Sam Hague
 

Anil,

are there any specific changes needed by OVSDB for clustering from MDSAL?

Trying to get the formal dependencies request in before this Thursday's M2 deadline.

Thanks, Sam

I think the only dependency from clustering perspective is controller project. Apart from that we don't have any specific dependency i believe.

Hi,
Not sure how is it implemented now, if i have a N nodes cluster and the ovsdb is connected to each of the N nodes, does each node in the N cluster persist the operational data to the Data Store?

Logically there is only one Operational/Config data store for all the nodes in the cluster. As of now persistence of operational data store is disabled, it only persist config data store.

Hi Anil,
Sorry, I meant "will each of the nodes write to the operational data store?" If ovsdb is connected to all the nodes, each will get the ovsdb notification and do a write transaction to the operational for the same data?

With the current implementation that's the case, because ovsdb is as of now is not cluster aware. But once we make it cluster aware, only one instance of ovsdb will be writing to data store.
