     * @apiNote
     * The DIRECT option enables performing file I/O directly between user
     * buffers and the file thereby circumventing the operating system page
     * cache and possibly avoiding the thrashing which could otherwise occur
     * in I/O-intensive applications. This option may be of benefit to
     * applications which do their own caching or do random I/O operations
     * on large data sets. It is likely to provide the most benefit when
     * the file is stored on a device which has high I/O throughput capacity.
     * The option should be used with caution however as in general it is
     * likely to degrade performance. The performance effects of using it
     * should be evaluated in each particular circumstance.
