Stable Media

JADE uses the Write‑Ahead Logging (WAL) protocol to maintain the Atomicity, Consistency, Isolation, and Durability (ACID) properties of the database and to ensure data integrity. WAL requires stable media capabilities. A storage solution must comply with this stable media intention.

In the event of system failures, it is vital that storage solutions used to host JADE database files and transaction journals guarantee that acknowledged write operations are non‑volatile, no matter what fails.

If this requirement is not met, data can be lost in the event of power failures or the resetting of the server. Such data loss can result in an irrecoverable file system or database corruption.
