Collection Setare the regions thatG1considers to look further at.G1, in themarkphase, will compute some metadata about each region, one of those metadata information is how much is alive in each of them. It also knows how much time it took on the previous run to reclaim dead objects in each region. To meet it's goals of timeouts, it selects the regions with the most garbage and processes them. Those regions are called:collection set.Relocation Setis basically the same thing, at least logically.ZGCselects regions (they call thempages) with most garbage. It first, under a stop-the-world event, relocates GC roots, and then, concurrently traverses thisRelocation Set.So in essence these are close to the same thing logically, since these GC are doing things quite differently, that is the bound where their similarities should be drawn, IMO.
