Jesus Camacho Rodriguez updated CALCITE-2858:
---------------------------------------------
Description:
In particular:
- JSON writer does not include information about literals type (unless the
literal is null). This can lead to some ambiguity when parsing the plan back
into RelNodes by the JSON reader. We will include this information in the
writer, and we will be able to parse it back in the reader.
- Decimal values are not printed/parsed back correctly; precision/scale is lost.
- There is no support for RexOver (window) clauses. This issue includes support
to print them in the writer and parse them back in the reader.
- Change visibility in some methods in RelJson to make it easier to override
some behavior in subclasses.
