-------------------------------
Summary: Allow deployers to configure a query time limit
Key: OAK-5978
URL: https://issues.apache.org/jira/browse/OAK-5978
Project: Jackrabbit Oak
Issue Type: New Feature
Components: query
Affects Versions: 1.6.1
Reporter: Ian Boston
Currently when a query takes a long time to complete, Oak allows it to continue
to completion, which can under certain circumstances result in resource
exhaustion and slow performance for all operations depending on Oak.
This feature request is to apply a deployer configurable time limit to all
queries. If the query exceeds that time limit, it is canceled with a suitable
exception, so that it consumes no more resources and the code or user that
submitted the query is notified.
Ideally this needs to work while the query is executing inside Oak rather than
waiting to return via the Oak API before being canceled. Cancelation should
result in minimal resource usage.
At this stage, this is an idea. It may not be possible to implement.
