[jira] [Commented] (ARROW-5033) [C++] JSON table writer

    [ https://issues.apache.org/jira/browse/ARROW-5033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17613847#comment-17613847 ] 

Steve M. Kim commented on ARROW-5033:
-------------------------------------

As part of this feature request, do we contemplate generating a [JSON Schema|https://json-schema.org/] from a Arrow table schema? Given an Arrow schema and record batches, it would be useful to get a JSON schema and a sequence of JSON objects that conform to that schema. This would also facilitate testing the correctness of the Arrow JSON writer.

> Users who need to emit json in line delimited format currently cannot do so using arrow. It should be straightforward to implement this efficiently, and it will be very helpful for testing and benchmarking
