>
> Multiple container moves can complete simultaneously, and each
> {{whenComplete}} callback executes in its own thread. The compound {{+=}}
> operation on a {{long}} is not atomic and can produce incorrect results.
> {code:java}
> future = future.whenComplete((result, ex) -> {
> metrics.incrementCurrentIterationContainerMoveMetric(result,1);
> moveSelectionToFutureMap.remove(moveSelection);
> if(ex !=null) {
> ... } else {
> if(result ==MoveManager.MoveResult.COMPLETED){
> sizeActuallyMovedInLatestIteration += // ← non-atomic
> containerInfo.getUsedBytes(); {code}
