Labels: ready-to-commit (was: )
> Add "message parsing" to new JSON loader
> ----------------------------------------
>
> Key: DRILL-7683
> URL: https://issues.apache.org/jira/browse/DRILL-7683
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.18.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
> Labels: ready-to-commit
> Fix For: 1.18.0
>
>
> Worked on a project that uses the new JSON loader to parse a REST response
> that includes a set of "wrapper" fields around the JSON payload. Example:
> {code:json}
> { "status": "ok", "results: [ data here ]}
> {code}
> To solve this cleanly, added the ability to specify a "message parser" to
> consume JSON tokens up to the start of the data. This parser can be written
> as needed for each different data source.
> Since this change adds one more parameter to the JSON structure parser, added
> builders to gather the needed parameters rather than making the constructor
> even larger.
