### Partial updates recap

In summary, to apply partial updates you would:

* (Optionally) use `PATCH` instead of `PUT`.
* Retrieve the stored data.
* Put that data in a Pydantic model.
* Generate a `dict` without default values from the input model (using `exclude_unset`).

   * <p>The entry set is backed by the same data as the multiset, so any change to either is
   * immediately reflected in the other. However, multiset changes may or may not be reflected in
   * any {@code Entry} instances already retrieved from the entry set (this is
   * implementation-dependent). Furthermore, implementations are not required to support
   * modifications to the entry set at all, and the {@code Entry} instances themselves don't even

   *
   * <ul>
   *   <li>{@code getStackTrace} takes {@code stackSize} time to return but then negligible time to
   *       retrieve each element of the returned list.
   *   <li>{@code lazyStackTrace} takes negligible time to return but then {@code 1/stackSize} time
   *       to retrieve each element of the returned list (probably slightly more than {@code
   *       1/stackSize}).
   * </ul>
   *

 *
 * <h3>Repositories</h3>
 *
 * <p>In Maven, <dfn>{@linkplain org.apache.maven.api.Repository repositories}</dfn> are locations where project artifacts (such as JAR files, POM files, and other
 * resources) are stored and retrieved. There are two primary types of repositories:<ul>
 *     <li><dfn>{@linkplain org.apache.maven.api.LocalRepository local repository}</dfn>: A directory on the developer's machine where Maven caches
 *     downloaded artifacts.</li>

 * create a dependency graph. First, only the root dependency can be given. Second, a root dependency and direct
 * dependencies can be specified in which case the specified direct dependencies are merged with the direct dependencies
 * retrieved from the artifact descriptor of the root dependency. And last, only direct dependencies can be specified in
 * which case the root node of the resulting graph has no associated dependency.
 *
 * @since 4.0.0
