I am processing serialized messages from SQS using Logstash. The messages have been serialized using a **FORWARD TRANSITIVE** schema. The schema may change in the future. To deserialize these messages, I'd like to use the Codec Avro Plugin, and a locally stored schema file on disk.

According to the documentation, the [Codec Avro Plugin](https://www.elastic.co/guide/en/logstash/current/plugins-codecs-avro.html#_decoding) does not support partial deserialization. Does this mean I can't use this plugin because a message using a X+1 version schema can't be deserialized using a X version schema?
