Key management: plan retirement before rotation
Changing the active key does not end historical dependencies.

Reading context
A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.
Original source ↗The architecture decision
Rotation may work for new writes while historical data still depends on old material. Removing a key without understanding those relationships can undermine recovery.
Practical application
Editorial proposal: map key versions to datasets and backups. In a hypothetical long-term archive, distinguish stopping encryption with a key from no longer needing it for reads.
How to verify
Before retirement, restore synthetic data representing older versions. Document approval ownership and supporting evidence. A useful indicator is not just key age, but understanding the dependencies that still justify keeping it.
