Description
We are using bigint data type as primary key now. But we will need two features in future:
- easy data migration / cloning between environments (preproduction - production)
- generatate primary key on client (cloning, offline access)
We want use uuid as PK, but before this, we need answers to:
- how index size grows - e.g. for two entities parent - child - ~50 milion records
- how insert time grows
...
Postgresql will be used for first test.

Using of guid is stable, but with some cons.
