## Using Akka Serialization for embedded types
For types that already have an Akka Serializer defined that are embedded in types serialized with Jackson the @apidoc[AkkaSerializationSerializer] and
@apidoc[AkkaSerializationDeserializer] can be used to Akka Serialization for individual fields.
The serializer/deserializer are not enabled automatically. The `@JsonSerialize` and `@JsonDeserialize` annotation needs to be added
to the fields containing the types to be serialized with Akka Serialization.
The type will be embedded as an object with the fields:
* serId - the serializer id
* serManifest - the manifest for the type
* payload - base64 encoded bytes
## Additional configuration
### Configuration per binding

### Conflict free replicated data types
TODO example once CRDTs are in
The following CRDTs are included that can be used to build your own data model:
* @apidoc[LwwTime]
* @apidoc[Counter]
* @apidoc[akka.persistence.typed.crdt.ORSet]
Akka serializers are included for all these types and can be used to serialize when @ref[embedded in Jackson](../serialization-jackson.md#using-akka-serialization-for-embedded-types).
