Subject [jira] [Commented] (DRILL-19) Build a JSON scanner that does schema discovery
Date Mon, 21 Jan 2013 19:16:13 GMT

    [ https://issues.apache.org/jira/browse/DRILL-19?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13559000#comment-13559000

Timothy Chen commented on DRILL-19:
-----------------------------------

My latest check in on Github I've more closely following Jacque's RecordIterator interface
and design.

I've also added a main method to play with ScanJson operator, which will output Full schema
and also schema diffs between each record (if different). 

I'm still changing the Protobuf output to use DescriptorProto, but feel free to take it and
play with it

> Build a JSON scanner that reads a file and converts it into two parts: a stream of records
and a schema which reflects the schema of the records.
