Hi Guys, I've got an Eventsourcing & CQRS based application. Not using DDD or Akka persistence (because of certain restrictions).
Has anyone tried storing the *State* of an *Actor* to local file system instead into a remote database (Like snapshotting in Akka-persistence) ? I was thinking of doing the following 1. *Command* arrives at *ActorA* 2. *ActorA* checks if it has a serialized *State* on local file system, if yes, it de-serializes the *State* and processes the *Command*, and then *ActorA *flushes it's *State* to disk holding only directory reference to the updated local serialized *State*. 3. If *State* does not exists on local file system then it replays all *Event*s from the database, process the *Command*,and then *ActorA *flushes it's *State* to disk holding only directory reference to the updated local serialized *State*. I see the following benefits in doing this 1. Much less memory usage since the state is not being kept in memory. 2. I don't have to worry much about killing Actors in real time since the State is only holding a String which is a reference to the locally serialized State's location and creating Actors is cheap. 3. Reduced trips to the database. 4. It's faster to read data locally since we know the location of the Serialized State, so probably help in building a speedy app :) Am I seeing this right ? Or there are some problems that I have not thought of ? Any experience with this ?
