> Key: DRILL-8005
> URL: https://issues.apache.org/jira/browse/DRILL-8005
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - JDBC
> Affects Versions: 1.19.0
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Major
> Fix For: 1.20.0
>
>
> Current implementation of Drill only allows writing to file systems. This
> issue proposes extending the JDBC plugin to allow writing to JDBC data
> sources. This will do so by implementing:
> CREATE TABLE AS
> DROP TABLE
