Subject [jira] [Commented] (DRILL-19) Build a JSON scanner that does schema discovery
Date Fri, 11 Jan 2013 00:50:12 GMT

    [ https://issues.apache.org/jira/browse/DRILL-19?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13550633#comment-13550633
] 

Jacques Nadeau commented on DRILL-19:
-------------------------------------

In the heterogeneous situation, you should just capture the array as type heterogeneous and
then encode the schema information with each element in the array. 

Random thought, what do you think about making your schema code output a proto idl?  For the
heterogeneous array option,  I'd use a type of repeated bytes with the assumption that each
bytes value will be the schema followed by the data.
