Subject [jira] [Commented] (IGNITE-5439) JDBC thin: support query cancel
Date Wed, 07 Nov 2018 08:39:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-5439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16677839#comment-16677839

Alexander Lapin commented on IGNITE-5439:
-----------------------------------------

Seems that we need to add prioritized cancel request processing.

For me it's not obvious of how to implement it. There are some options, including:
 * shift all non-priority queries to another pool;
 * add some sort of query filtering, in order to move cancel queries to specific pool;

However, none of given solutions are good enough. [~vozerov] any ideas?
