Affinity key for specific node

[Mikael <mi...@telia.com>]

Hi!

I have a singleton service running on a specific node, It access a 
serial port so it must be running on that specific node so I can't use 
affinity key for the service, now I want to create some values in a 
cache that will be used by the service, is there any way I can create 
affinity keys for those values so they will end up in the cache on the 
same node as the service ?

Mikael,

You can also use a replicated cache then. This will give you both: all data
available on service node as well as failover in case of failure (you will
not lose any data as long as there is at least one node available).

Well, I would like to use a partitioned cache so that the data in the 
cache stays intact if that node goes down for a while, but if more nodes 
go down it might be lost anyway so maybe I need to use a local cache and 
persist it instead, was trying to avoid that.

If it's a single node, I would just create a special local cache for these
entries and deploy it on that node. Will this work?
