-------------------------------------
Summary: Better documentation describing the accepted JSON data
input
Key: DRILL-1284
URL: https://issues.apache.org/jira/browse/DRILL-1284
Project: Apache Drill
Issue Type: Improvement
Components: Documentation
Affects Versions: 0.4.0
Reporter: Luca Morandini
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 documentation.
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
