Description

A repository with continuous writes can keep the compactor from completing causing the repository size to grow indefinitely.

This effect is caused by the compactor trying to catch up with changes that occurred while compacting. I.e. compacting them on top of the already compacted head. When there is a steady stream of incoming changes it can happen that the compactor never actually catches up.
