Hi I am working on a streaming project where I need to consume different source types on demand. To comply with the akka model I decided to implement dedicated mailbox types which establish a connection with the desired source and read data from it, eg. kafka topics or websockets. As I do not know which source to consume before starting the application I cannot provide the full configuration parameters but need to set them during runtime.
What I would like to know is, if there is a chance to get configuration data into a mailbox when it is instantiated. The data must not be read from a configuration file but may be provided by the caller on demand. The only solution I actually thought of was to ramp up the actor + mailbox without any configuration and send a message holding the configuration right after its instantiation. The mailbox sees the message, extracts the information and configures the source listener as required. The message might be removed from the mailbox or be provided to the actor - depends on spec. In some way I dislike this solution as it makes me react to messages on two different layers: the mailbox and the actor. I tried to establish the source connection from within an actor, scheduled READ MESSAGES to itself and on receiving this message type the actor takes a single message from the source. The drawback of this solution is a reduced throughput as each READ MESSAGE must be awaited and then the source must be consumed. It allows to throttle the reading speed but it does not allow to speed things up arbitrarily as the READ MESSAGE must be issued .. which takes time :-( Aside from that I must provide another managing layer which handles the reading actors. Therefore I'd love to use the mailbox approach but find it quite annoying to send in control messages.
