Konstantin Orlov updated IGNITE-21230:
--------------------------------------
Description:
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
