> Add Query Metadata to RESTful Interface
> ---------------------------------------
>
> Key: DRILL-6847
> URL: https://issues.apache.org/jira/browse/DRILL-6847
> Project: Apache Drill
> Issue Type: Improvement
> Components: Metadata
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Minor
>
> The Drill RESTful interface does not return the structure of the query
> results. This makes integrating Drill with other BI tools difficult because
> they do not know what kind of data to expect.
> This PR adds a new section to the results called Metadata which contains a
> list of the minor types of all the columns returned.
> The query below will now return the following in the RESTful interface:
> {code:sql}
> SELECT CAST( employee_id AS INT) AS employee_id,
> full_name,
> first_name,
> last_name,
> CAST( position_id AS BIGINT) AS position_id,
> position_title
> FROM cp.`employee.json` LIMIT 2
> {code}
> {code}
> {
> "queryId": "2414bf3f-b4f4-d4df-825f-73dfb3a56681",
> "columns": [
> "employee_id",
> "full_name",
> "first_name",
> "last_name",
> "position_id",
> "position_title"
> ],
> "metadata": [
> "INT",
> "VARCHAR",
> "VARCHAR",
> "VARCHAR",
> "BIGINT",
> "VARCHAR"
> ],
> "rows": [
> {
> "full_name": "Sheri Nowmer",
> "employee_id": "1",
> "last_name": "Nowmer",
> "position_title": "President",
> "first_name": "Sheri",
> "position_id": "1"
> },
> {
> "full_name": "Derrick Whelply",
> "employee_id": "2",
> "last_name": "Whelply",
> "position_title": "VP Country Manager",
> "first_name": "Derrick",
> "position_id": "2"
> }
> ]
> }
> {code}
