Memcache use case?

What are the use cases for the memcache with foreman plug-in ? I can’t find any docs on what types of scenarios it would improve and don’t want to preemptively optimize and over complicate. Is it for large puppet installs or help more with things like remote execution?

Foreman doesn’t cache that much, but it is needed to keep multiple servers behind a load balancer in sync. I’d say that for most users having the cache on tmpfs (default at least for RPM deployments, not 100% sure about deb) is good enough.
