Memcached itself does not handle any fail over. Whatever is handling the
fail over you speak of, is in the client library used by Tomcat or in
the session handling code in Tomcat. It is not part of memcached.

Hi Daniel,
We use AEM installed on Tomcat with memcache. I am refering to web
sessions in my question below.
The failover setup is as per industry standard. My question is more
around session management between Tomcat and Memcache configuration and
not on the general failover setup.

Subject: Re: Multiple failoverNodes
I think your question is missing some details. For instance, what do
you mean sessions? Web sessions? Cookies?
Regardless, the deeper question is: what tooling are you using to manage
your clustering / failover behavior? I'm guessing your questions would
be more appropriate for that group.

Hi,
Can there be multiple failover nodes setup in case of
sticky/non-sticky sessions?
I.e., if there are 4 nodes I would like to have each node have more
than 1 fail over node, so that when a rolling restart is done during
deployments on 2 nodes at a time there will not be any session loss.
As the 2 nodes that are picked at a time could be the primary &
secondary nodes for a particular session and hence will result in
session loss if restarted.
Is there a configuration that allows us to set the number of fail
over nodes/levels in case of both sticky/non-sticky sessions?
Regards,
Deepthi
