I need akka cluster because — My application is an IVR where http requests flow between the caller and the api (a new http request-response for each spoken sentence basically). The load balancer randomly chooses an instance and forwards the request. If i do not use akka-sharding-persistence-cluster then i need to re-create the conversation state every time. Each conversation lasts for 3–4 minutes with 10–15 avg round trips of request-response.

Any thoughts on what other tech stack could be useful here?
