[jira] [Commented] (DRILL-105) JDBC Storage engine

    [ https://issues.apache.org/jira/browse/DRILL-105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13699354#comment-13699354 ] 

Julian Hyde commented on DRILL-105:
-----------------------------------

Consider using Optiq's JDBC adapter. There is quite a lot of complexity: how to flatten the algebra tree into a small number of query blocks, how to map data types, how to know which built-in functions are supported in the target database.

> We should allow query pushdown into JDBC.  Note that this is very different from JDBC support that allows a Java program to send a query to Drill.  Instead, it is a way for Drill to push down a query into a JDBC driver.
