This changes the compaction scheduling to better utilize the available cores that are free. Previously, a level was planned in its own goroutine and would kick off a number of compactions groups. The problem with this model was that if there were 4 groups, and 3 completed quickly, the planning would be blocked for that level until the last group finished. If the compactions at the prior level are running more quickly, a large backlog could accumlate. This now moves the planning to a single goroutine that plans each level in succession and starts as many groups as it can. When one group finishes, the planning will start the next group for the level. |
