[jira] [Commented] (OAK-382) JMX service to listing and cancel long running queries

    [ https://issues.apache.org/jira/browse/OAK-382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13879991#comment-13879991 ] 

Thomas Mueller commented on OAK-382:
------------------------------------

Instead of having to cancel the long running query manually using JMX, an option is to automatically cancel them (throw an exception) if they traverse a configurable number of nodes, or if it is known in advance that they would have to traverse many nodes (for example if there is no index, and the whole repository would have to be traversed).

> Queries can potentially run for a very long time. I suggest we provide a way to list the running queries, and to cancel them using JMX.
