Method ConsumeLocal

be/src/runtime/mem-tracker.h:159–163

Increases the consumption of this tracker and the ancestors up to (but not including) end_tracker. This is useful if we want to move tracking between trackers that share a common (i.e. end_tracker) ancestor. This happens when we want to update tracking on a particular mem tracker but the consumption against the limit recorded in one of its ancestors already happened.

  /// to update tracking on a particular mem tracker but the consumption against
  /// the limit recorded in one of its ancestors already happened.
  void ConsumeLocal(int64_t bytes, MemTracker* end_tracker) {
    DCHECK_GE(bytes, 0);
    if (UNLIKELY(bytes < 0)) return; // needed in RELEASE, hits DCHECK in DEBUG
    ChangeConsumption(bytes, end_tracker);
  }

  /// Same as above, but it decreases the consumption.
  void ReleaseLocal(int64_t bytes, MemTracker* end_tracker) {
