IIUC, the goal is to separate task-level parameters and process-level parameters. However, I don't see how this PR can help since we still have CompactorContext storing all the parameters. This PR is somehow preliminary and just modifies severl method to accept handcrafted parameters instead of CompactorContext. I suggest we work on a PR for parameter separation as a whole.

It seems redundant to clone the metric and define two variables here.

Close as #12020 is more reasonable
