I don't see the affinity between microservices and locality. Any kind of distributed storage, including cache, is going to include a choice about how data are partitioned, ordered, and indexed. If you want certain records to be in memory on the same nodes, you should not need a separate cache cluster to accomplish that, let alone a separate cache service implementation.
