>
> General logic of metastorage is that it supports multiple versions for the
> same key corresponding to different timestamps.
> At the same time there is a concept of a low watermark - a moment in time
> when all timestamps falling below that mark become obsolete and can be pruned
> from Metastorage.
> We need to implement a mechanism to compact Metastorage to remove obsolete
> keys. At the same time some components may rely on availability of history of
> key's versions.
