Description

Relational expression Exchange has a distribution field. When serializing to/from json this field can not be serialized properly.

The distribution field is a RelDistribution which contains a type and a list of key indexes.

Add methods to RelJson:

RelDistribution toDistribution(Map<String, Object> map){...}
Object toJson(RelDistribution relDistribution) {...}
