#### Key rotation

S3 clients can change the client-provided key of an existing object. Therefore an S3 client must perform a S3 COPY operation where the copy source and destination are equal. Further the COPY request headers must contain the current and the new client key:

      public void run() {
        thirdSignal.countDown();
        result.set(1, cache.getUnchecked(key));
        doneSignal.countDown();
      }
    }.start();

    // give the second get a chance to run; it is okay for this to be racy
    // as the end result should be the same either way
    thirdSignal.await();
    Thread.yield();

    // Expand!
    CacheTesting.forceExpandSegment(cache, key);

    }
  }

  /*
   * We've split testFuzzyCompare() into multiple tests so that our internal Android test runner has
   * a better chance of completing each within its per-test-method timeout.
   */

  public void testFuzzyCompare0() {
    runTestFuzzyCompare(0);
  }

  public void testFuzzyCompare1() {
    runTestFuzzyCompare(1);
  }

Previous versions of FastAPI (before <abbr title="before 2023-03">0.95.0</abbr>) required you to use `Query` as the default value of your parameter, instead of putting it in `Annotated`, there's a high chance that you will see code using it around, so I'll explain it to you.

/// tip

For new code and whenever possible, use `Annotated` as explained above. There are multiple advantages (explained below) and no disadvantages. 🍰

* the workload

* the deployment
* to deploy

* the SDK
* the software development kit

* the button
* the callable
* the code
* the commit
* the context manager
* the coroutine
* the database session
* the disk
* the domain
* the engine
