Cette simplicité et cette flexibilité permettent d'utiliser des bases de données NoSQL comme principal système de stockage de données.

Comme il est très simple, son apprentissage est relativement intuitif, bien que la documentation soit quelque peu
technique par moments.

   * <p>Whenever possible, it is preferable to test directly for some observable change resulting
   * from GC, as with {@link #awaitClear}. Because there are no guarantees for the order of GC
   * finalization processing, there may still be some unfinished work for the GC to do after this
   * method returns.
   *
   * <p>This method does not create any memory pressure as would be required to cause soft
   * references to be processed.
