[jira] [Commented] (DRILL-624) Use Header rows (if exists) as metadata for the text readers

["Hari Sekhon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14212153#comment-14212153 ] 

Hari Sekhon commented on DRILL-624:
-----------------------------------

This should be configurable via a keyword per SQL query since if you configure it at the storage plugin level then it'll apply to all fields.

Having a session variable for it would also be useful but the query override is non-optional IMHO.

> Currently the text readers return the data as array all the time. A lot of times, the source text files can have header rows which identify the field names/metadata for the data. 
> If this exists, Drill should leverage it to provide the query experience on this metadata directly (just like parquet or JSON).
