I am working on a project with around 2m record. I use aggregation framework to manipulate the whole collection to generate a report. This aggregation query takes a while, but I don't want to block the db from serving requests from normal users. I don't mind if the generation process takes longer, so may I know if it is possible to just allocate certain system resources for one aggregation query which is supposed to take a long time ? |

witmoyl, there's currently no facility to limit resources for aggregation operations, but those should not block other users or operations. If you're concerned about performance impact you may want to consider using a replica set and run your aggregation report on a secondary node.
