             Summary: Support Clickhouse using RDBMS Storage Plugin
                 Key: DRILL-7984
                 URL: https://issues.apache.org/jira/browse/DRILL-7984
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - JDBC
            Reporter: wtf
            Assignee: wtf


Trino(Formerly PrestoSQL, branched from Presto) has already supportted 
[Clickhouse|[https://trino.io/docs/current/connector/clickhouse.html]|https://trino.io/docs/current/connector/clickhouse.html],]
 using 
[clickhouse-jdbc|[https://github.com/ClickHouse/clickhouse-jdbc]|https://github.com/ClickHouse/clickhouse-jdbc]

When connecting to clickhouse using drill jdbc plugin, found one uncompatible 
place:

clickhouse jdbc map return constant string "default" when call getCatalogs, and 
return databases when call getSchemas(input catalog is not used). All schemas 
will be appended after the "default" catalog, which will cause the query to 
fail.

This Jira will try to address the uncompatibility when connecting to clickhouse 
using jdbc plugin.
