Akka.Persistence.MongoDB v1.4.0-beta3

1.4.0-beta3 February 04 2020

Introduced legacy serialization modes.

Going from v1.4.0 onwards, all events and snapshots are saved as byte arrays using the standard Akka.Persistence format.

However, in the event that you have one of the following use cases:

1. Legacy data all stored in the original BSON / "object" format;
2. A use case where BSON is preferable, i.e. so it can be queried directly via MongoDb queries rather than Akka.Persistence.Query; or
3. A requirement to keep all data in human-readable form.

Then you can disable binary serialization (enabled by default) via the following HOCON:

akka.persistence.mongodb{
   journal{
    legacy-serialization = off
  }

  snapshot-store{
   legacy-serialization = off
 }
}

Setting legacy-serialization = on will allow you to save objects in a BSON format.

WARNING: However, legacy-serialization = on will break Akka.NET serialization. IActorRefs, Akka.Cluster.Sharding, AtLeastOnceDelivery actors, and other built-in Akka.NET use cases can't be properly supported using this format. Use it at your own risk.
