Subject [jira] [Commented] (DRILL-1284) Better documentation describing the accepted JSON data input
Date Tue, 12 Aug 2014 03:59:12 GMT

    [ https://issues.apache.org/jira/browse/DRILL-1284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14093699#comment-14093699

Jacques Nadeau commented on DRILL-1284:

Slight updates:

(1) we should support a single record over many lines.  The record separator is  }\W{
(3) This should work fine and shouldn't need to be documented.  If it does not, this is a
bug.  [~sollala_drill], can you please verify this?

> Since JSON data input can be very diversified, and Drill, so far, accepts only tuples
defined in one mongimport format, it would be useful to have this clearly spelled out in the
> This improvement to the documentation should stress:
> # The accepted JSON input format (single Objects describeing tuples, every one of them
in a single line, with no separator between lines);
> # The homogeneous Arrays constraint: only elements of the same type are accepted in a
JSON array in Drill;
> #  The need to address a single element of a JSON array in a Drill SQL query: {{SELECT
foo\[2\] FROM bar.json}} is accepted, {{SELECT foo FROM bar.json}} is not
