Hi Everyone,
I have question or few regarding process of Cissco APIC shard election.
In Cisco APIC design guide I found few information as below :
"In a Cisco APIC cluster, there is no one Cisco APIC that acts as a leader for all shards. For each replica, a shard leader is elected, with write operations occurring only on the elected leader. Therefore, requests arriving at a Cisco APIC are redirected to the Cisco APIC that carries the shard leader."
How does leader is elected for Cisco APIC Cluster ?
Also there is information as below :
"Each replica in the shard has a use preference, and write operations occur on the replica that is elected leader. Other replicas are followers and do not allow write operations."
Is it possible to check these preference or is there way to set those preference manually ?
How does it work ?
I would appreciate if anyone have knowledge and can share it with all of us as I think that this knowledge would be beneficial for others in the future.
Thank you
