TJ Banghart updated CALCITE-5514:
---------------------------------
Description:
CALCITE-5349 added several improvements for creating
{{org.apache.calcite.rel.externalize.RelJson}} such as the {{withOperatorTable,
withLibraryOperatorTable}} and, {{withJsonBuilder}} methods.
However, the only method to deserialize JSON with the {{RelJson}} class is a
the {{static}} {{readExpression()}} which creates a generic {{RelJson}}.
It would be advantageous to have a {{RelJson}} instance method capable of
deserializing JSON into a {{RexNode}} after it has been customized.
