Since append-only writes are strictly sequential and do not necessitate seeking, they can be performed at any time without interruption. All writes are read-throughs [spin the wheel](https://spin-thewheel.com/) . The disk-based data file is appended whenever a value is modified, and the in-memory key index is subsequently updated to reflect the new location of the file.
