Hi, are we losing asks and bids here?

Yes, absolutely - had to disable that serialization when using standard MongoDB polymorphic representation. If I followed through with using the Protobuf serialization all the way through then that would not be an issue.

Aaron, you mean something like TradeEventSerializer but for the MatchingEngine in conjunction with the appropriate configuration like https://getakka.net/articles/persistence/custom-serialization.html

Yep! That's correct - we did that with some of the events here: https://github.com/petabridge/akkadotnet-cluster-workshop/blob/dev/src/Akka.CQRS/Serialization/TradeEventSerializer.cs

For the pricing engine, I actually defined all of the protos and compiled them here: https://github.com/petabridge/akkadotnet-cluster-workshop/tree/dev/src/Akka.CQRS.Pricing/Serialization/Proto

But I never got around to writing the full serializer - ran short on time before we had to present this live the very first time.
