Subject [jira] [Commented] (BEAM-626) AvroCoder not deserializing correctly in Kryo
Date Mon, 12 Sep 2016 17:32:20 GMT


Aviem Zur commented on BEAM-626:

It does have such a fallback, but seems to only be for Externalizable classes:

>                 Key: BEAM-626
>                 URL:
>             Project: Beam
>          Issue Type: Bug
>          Components: sdk-java-core
>            Reporter: Aviem Zur
>            Assignee: Davor Bonaci
>            Priority: Minor
> Unlike with Java serialization, when deserializing AvroCoder using Kryo, the resulting
AvroCoder is missing all of its transient fields.
> The reason it works with Java serialization is because of the usage of writeReplace and
readResolve, which Kryo does not adhere to.
> In ProtoCoder for example there are also unserializable members, the way it is solved
there is lazy initializing these members via their getters, so they are initialized in the
deserialized object on first call to the member.
> It seems AvroCoder is the only class in Beam to use writeReplace convention.
