Describe the feature you'd like

Currently some background tasks such as index building are not run in task executor, but a separate thread pool is started to run them. This is not good for unified management of compute resources. The goal of this feature request is to unify some background tasks and run them on the task executor. At the same time, the foreground tasks will have a higher priority, and can be scheduled and executed by the task executor first.
