Filtering as domain logic
Read OriginalThe article discusses the design challenge of implementing complex filter logic for database queries. It proposes a dual approach: using a simple, performant server-side query (e.g., SQL) for initial filtering, and implementing the more complex, correctness-critical filtering logic in an easily testable in-memory client library. This balances performance with robust verification through standard software engineering practices like TDD and property-based testing.
