_Netflix_, for example, developed two new staging committers - the Directory staging committer and the Partitioned staging committer - to take full advantage of native object storage operations. These committers do not require rename operation. The two staging committers were evaluated, along with another new addition called the Magic committer for benchmarking.

It was found that the directory staging committer was the fastest among the three, S3A connector should be configured with the following...

## Einfache Verwendung

Näher betrachtet, werden *Pfadoperation-Funktionen* deklariert, um verwendet zu werden, wann immer ein *Pfad* und eine *Operation* übereinstimmen, und dann kümmert sich **FastAPI** darum, die Funktion mit den richtigen Parametern aufzurufen, die Daten aus der Anfrage extrahierend.

   * which is still better than alternatives.
   *
   * Per-thread hash codes are initialized to random values.
   * Contention and/or table collisions are indicated by failed
   * CASes when performing an update operation (see method
   * retryUpdate). Upon a collision, if the table size is less than
   * the capacity, it is doubled in size unless some other thread
   * holds the lock. If a hashed slot is empty, and lock is
