> 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.
