> Currently, catalog uses java's built-in serialisation in order to persists
> descriptors and update entries. Although it is most simple way to address
> conversion of POJO to byte array, the built-in serialisation is not efficient
> in terms of occupied space. Given that catalog may contain thousands and
> thousands of objects, it may result in increased load on a metastorage.
> To address this issue, let's introduce custom serialisation format for
> catalog's descriptors and update entries.
> NB: we should keep in mind that descriptors may evolve over time, thus we
> should consider support of versioning for descriptors
