Thomas Mueller commented on OAK-8294: ------------------------------------- [~catholicon] sorry for the delay. > exact string matches I see. I would be very user-friendly I agree, on the other hand it is less flexible... In your example, in theory the "AND [foo]=" could be in quotes, so by mistake it would also match for example {noformat} SELECT * FROM [some:Type] WHERE [rel/path/foo]=' some test AND [foo]='' some other text ' {noformat} I know regular expressions are not very user friendly and tricky to get right... But flexible. That said, I will try to implement your approach as well, I think it would be so much easier. Meaning, try to support both regular expressions as well as patterns as you describe. > Make it possible to mark a (customer) query as bad and skip it > -------------------------------------------------------------- > > Key: OAK-8294 > URL: https://issues.apache.org/jira/browse/OAK-8294 > Project: Jackrabbit Oak > Issue Type: New Feature > Components: query > Reporter: Thomas Mueller > Assignee: Thomas Mueller > Priority: Major > Attachments: OAK-8294.patch > > > Application code can run all kinds of bad queries (reading a lot of data, > slow, high memory usage). > The best solution is to fix the application of course. But that can take a > while, and until this is done, it would be good if bad queries can be blocked > in another way. Problematic queries would either just log a warning, or be > blocked (throw an exception when trying to run). > Blocking should be possible via JMX, but also via persistent configuration > (in the repository), so that a restart remembers which queries are blocked. > I don't think it's needed to stop already running queries, as the traversal > limit should solve this (it can be re-configured at runtime if needed). Also, > reading the patterns from the repository is only needed at startup (while > running, JMX can be used to temporarily add patterns). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
