> Improvements in JSON writer and reader for plans
> ------------------------------------------------
>
> Key: CALCITE-2858
> URL: https://issues.apache.org/jira/browse/CALCITE-2858
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.19.0
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> 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.
