> If I'm not wrong, the UPSERT method of memStore should remove all existing
> KeyValues except the newer version.
> In memStore,
> {code:title=DefaultMemStore.java|borderStyle=solid}
> int versIionsVisible = 0;
> ...
> if (cur.getTypeByte() == KeyValue.Type.Put.getCode() &&
> cur.getSequenceId() <= readpoint) {
> if (versionsVisible > 1) {
> // if we get here we have seen at least one version visible to
> the oldest scanner,
> // which means we can prove that no scanner will see this version
> // false means there was a change, so give us the size.
> long delta = heapSizeChange(cur, true);
> addedSize -= delta;
> this.size.addAndGet(-delta);
> it.remove();
> setOldestEditTimeToNow();
> } else {
> versionsVisible++;
> }
> {code}
> Does "versionsVisible > 1" should be changed to "versionsVisible >= 1" ?
> thanks.
