final case classUnknownMetaData(serializerId: Int, manifest: String) extends Product with Serializable
If meta data could not be deserialized it will not fail the replay/query.
The "invalid" meta data is represented with this UnknownMetaData and
it and the event will be wrapped in EventWithMetaData.
The reason for not failing the replay/query is that meta data should be
optional, e.g. the tool that wrote the meta data has been removed. This
is typically because the serializer for the meta data has been removed
from the class path (or configuration).
