Subject [jira] [Commented] (DRILL-2373) JSON query request returns all types as strings
Date Tue, 14 Apr 2015 15:18:12 GMT

Jason Altekruse commented on DRILL-2373:
----------------------------------------

Completely agree, we are solving a lot of the same issues that consumers of JSON APIs in drill
itself, it makes no sense to re-introduce poor typing for consumers of our output. You might
be interested in taking a look at a feature currently in review to add extended JSON support,
to allow us to read in an export a greater variety of data types, similar to the approach
taken by MongoDB. DRILL-2695

> I'm not sure if the query JSON endpoint is a valid, documented feature of Drill, but
at the moment it returns all results as strings.
> So, for example:
> {code}select count(*) from cp.`employee.json`{code}
> Will return "1155" (as a string) as opposed to 1155 (as a numeric JSON value).
> It really should be returning numeric values as proper JSON numeric values.  Same should
apply for boolean values.
> How we handle other data types (i.e. dates, intervals, timestamps, etc.) needs discussion.
