> Currently, valid disk component are determined by their validity bit. However, if a crash happens in the small window after the validity bit is set but before the index checkpoint is updated, the component shouldn't be considered valid. This can be avoided by cleaning any components that have greater timestamp than the checkpoint valid component timestamp on node startup. This will also give the advantage of cleaning any index invalid components without having to active the index.
