Subject [jira] [Created] (IMPALA-5550) Session level SET LIMIT in ODBC/JDBC connections
Date Wed, 21 Jun 2017 14:32:00 GMT
Ninad Shringarpure created IMPALA-5550:

             Summary: Session level SET LIMIT in ODBC/JDBC connections
                 Key: IMPALA-5550
             Project: IMPALA
          Issue Type: Improvement
          Components: Clients
            Reporter: Ninad Shringarpure
            Priority: Minor

When using Impala in user dashboards like Tableau, users have an ability to write custom queries.
In some cases when users due to lack of knowledge or understanding write bad queries returning,
in some cases, billions of rows there has to be an ability to safeguard against this.

A session level setting in ODBC connection provided like SET LIMIT=100000 get help limit such
issues and accidental resource consumption in the cluster.
