+With many of the storage adapters you will also need to set the `namespace` option to `undefined` to have it work correctly. This is because in `v5` we started the transition to having the storage adapter handle the namespacing and `Keyv` will no longer handle it internally via KeyPrefixing. Here is an example of doing ith with `KeyvSqlite`:
+
+```js
+import Keyv from 'keyv';
+import KeyvSqlite from '@keyv/sqlite';
+
+const store = new KeyvSqlite('sqlite://path/to/database.sqlite');
+const keyv = new Keyv({ store });
+keyv.useKeyPrefix = false; // disable key prefixing
+store.namespace = undefined; // disable namespacing in the storage adapter
+
+await keyv.set('foo', 'bar'); // true
+await keyv.get('foo'); // 'bar'
+await keyv.clear();
+```
