Since upgrading our JBoss server, we sometimes we see thousands of Timer threads in the application server. Disabling QueryTimout is the current workaround
|Who would benefit from this IDEA?||As a customer I will be pleased by better performance while using less system resources for the JDBC driver, we can re-enable QueryTimeout as a safety net for protect against long-running queries in the database server.|
How should it work?
Instead of creating a new Timer object (which creates a new Thread) for each sql request, it should be possible to reuse either a singe Timer instance, or a fixed pool of Executors.
The benefits would be a faster driver with less resources, and still have the safety net of QueryTimeout
The current workaround is to disable QueryTimeout
|Priority Justification||We have OutOfMemory errors in production when QueryTimeout is enabled|
|Client Name||PostNord AS|
