Service Fabric Stateful Service

I noticed Eventstore has a similar patter to Service Fabric eg a primary writer and fall over capable multiple readers.

Is it possible to get an event of the Embedded EventStore changing to primary ? Then the normal SF name resolution will route web API writers to the node hosting the primary automatically.

Also any thoughts between hosting the store as an Exe vs using the Inproc store, The big attraction of the In Proc store is smooth integration into our infrastructure eg logging , config etc , D:\Data drive which is backed up along with the SF reliable collections. .

Has anyone else done this ?
