Hi Community, In Apache Beam we are facing a use case where we need to keep RexNode in our distributed primitives. Because of the nature of distributed computing, Beam requires the usage of those primitives be serializable (thus those primitives can be sent over the network to backend/workers for further execution).
In the Java world this requirement means to make RexNode implement the Java Serializable interface. A workaround right now is to create a bunch of classes to "clone" RexNode while making those classes implement the Serializable interface. So what do you think of the idea that makes RexNode implement the Serializable interface? -Rui
