paul-rogers opened a new pull request #2045: DRILL-7683: Add "message parsing" to new JSON loader URL: https://github.com/apache/drill/pull/2045 # [DRILL-7683](https://issues.apache.org/jira/browse/DRILL-7683): Add "message parsing" to new JSON loader ## Description 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: ``` { "status": "ok", "results: [ data here ]} ``` 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. Note that, aside from the private plugin mentioned above, no other code uses the JSON loader yet. ## Documentation N/A ## Testing Added unit tests. Reran all existing tests.
