Avoid iteration entirely by using db.keys()[0] and db.keys()[-1] with header key handling. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fix min/max validator append bug: validators were appended on every
__set__ call causing list to grow indefinitely. Moved to __call__
where they are set up once at class definition time.
- Replace contextlib.suppress with try/except in __get__ to avoid
context manager overhead on every attribute access.
- Add AutoField.compute_id() static method and use it in get() and
exists() to avoid creating temporary AutoField instances.
- Optimize update() to work directly with serialized data instead of
deserializing the full model and re-serializing.
- Optimize all() to batch-read all records in a single db session
instead of opening/closing the db for each record.
- Replace lazy __import__("uuid") with module-level import.
