             Summary: Support Query Level Options
                 Key: DRILL-6149
                 URL: https://issues.apache.org/jira/browse/DRILL-6149
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Timothy Farkas
            Assignee: Venkata Jyothsna Donapati

Currently the line between session options and query level options are blurred. 
Ideally a session level option can be set and persisted for the duration of a 
user's session. A query level option can be set for a query. Right now there is 
no explicit query level option. A query level option is a session option whose 
validator has a non zero ttl. We should change this to have options that belong 
to the Query Scope as defined in the OptionDefinition. The ttl should also be 
configurable by the user in their **alter set** command.
