-------------------------------------
Summary: Specify, as part of the query, table information: data
format (CSV, parquet, JSON. etc.), field delimiter, etc.
Key: DRILL-4659
URL: https://issues.apache.org/jira/browse/DRILL-4659
Project: Apache Drill
Issue Type: Improvement
Components: Query Planning & Optimization, SQL Parser
Reporter: Roger Dielrton
Priority: Minor
I have a file, that I would like to use in a query, and it can have one or more
of the
following properties:
* Has not extension ==> Drill is unable to handle it.
* I know it contains data in CSV format, but with an non standard character as
field separator ==>
Drill is unable to parse it (without modify the storage plugin configuration).
* Is located in an Amazon S3 bucket ==> I can rename it.
* Has a big size ==> It would be expensive to make a copy of it.
It would be nice if you can specify, as part of the "select" query, as
metadata, relevant table
information as:
* Data format (CSV, parquet, JSON. etc.)
* Field delimiter.
