> {{DataDomainFlushAction}} is a big chunk of code that is hard to maintain and to change. We need a better version to be able to support it and fix issues we already have (flattened attributes update, long flattened path, etc.)
> The idea is to create some intermediate representation of operations we should perform on DB layer and work with them, rather than trying to do everything with Persistent objects.
> Ideally this should be fully compatible with existing logic in terms of generated SQL batch queries.
