Subject [jira] [Created] (IGNITE-8595) SQL: Ability to cancel DDL operations
Date Thu, 24 May 2018 09:41:00 GMT
Vladimir Ozerov created IGNITE-8595:
---------------------------------------

             Summary: SQL: Ability to cancel DDL operations
                 Key: IGNITE-8595
                 URL: https://issues.apache.org/jira/browse/IGNITE-8595
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Vladimir Ozerov
             Fix For: 2.6


At the moment it is impossible to cancel DDL operations. Suppose that you started {{CREATE
INDEX}} on very heavy table. It took hours to finish, and you would like to stop it because
it is 9:00AM, and users are about to execute many queries and {{CREATE INDEX}} will slow them
down or even block.

It should be possible to stop DDL operations in the same way it is done for {{SELECT}} queries.
