+   * <li>target size is in the range of
+   *   (max_bytes_for_level_base / max_bytes_for_level_multiplier,
+   *    max_bytes_for_level_base]</li>
+   * <li>target size of the last level (level num_levels-1) equals to extra size
+   *    of the level.</li>
+   * </ol>
+   *
+   * <p>At the same time max_bytes_for_level_multiplier and
+   * max_bytes_for_level_multiplier_additional are still satisfied.</p>
+   *
+   * <p>With this option on, from an empty DB, we make last level the base
+   * level, which means merging L0 data into the last level, until it exceeds
+   * max_bytes_for_level_base. And then we make the second last level to be
+   * base level, to start to merge L0 data to second last level, with its
+   * target size to be {@code 1/max_bytes_for_level_multiplier} of the last
+   * levels extra size. After the data accumulates more so that we need to
+   * move the base level to the third last one, and so on.</p>
+   *
+   * <h2>Example</h2>
+   * <p>For example, assume {@code max_bytes_for_level_multiplier=10},
+   * {@code num_levels=6}, and {@code max_bytes_for_level_base=10MB}.</p>
+   *
+   * <p>Target sizes of level 1 to 5 starts with:</p>
+   * {@code [- - - - 10MB]}
+   * <p>with base level is level. Target sizes of level 1 to 4 are not applicable
+   * because they will not be used.
+   * Until the size of Level 5 grows to more than 10MB, say 11MB, we make
+   * base target to level 4 and now the targets looks like:</p>
+   * {@code [- - - 1.1MB 11MB]}
+   * <p>While data are accumulated, size targets are tuned based on actual data
+   * of level 5. When level 5 has 50MB of data, the target is like:</p>
+   * {@code [- - - 5MB 50MB]}
+   * <p>Until level 5's actual size is more than 100MB, say 101MB. Now if we
+   * keep level 4 to be the base level, its target size needs to be 10.1MB,
+   * which doesn't satisfy the target size range. So now we make level 3
+   * the target size and the target sizes of the levels look like:</p>
+   * {@code [- - 1.01MB 10.1MB 101MB]}
+   * <p>In the same way, while level 5 further grows, all levels' targets grow,
+   * like</p>
+   * {@code [- - 5MB 50MB 500MB]}
+   * <p>Until level 5 exceeds 1000MB and becomes 1001MB, we make level 2 the
+   * base level and make levels' target sizes like this:</p>
+   * {@code [- 1.001MB 10.01MB 100.1MB 1001MB]}
+   * <p>and go on...</p>
+   *
+   * <p>By doing it, we give {@code max_bytes_for_level_multiplier} a priority
+   * against {@code max_bytes_for_level_base}, for a more predictable LSM tree
+   * shape. It is useful to limit worse case space amplification.</p>

-   *
-   * <p>With this option on, from an empty DB, we make last level the base
-   * level, which means merging L0 data into the last level, until it exceeds
-   * max_bytes_for_level_base. And then we make the second last level to be

-   * target size to be {@code 1/max_bytes_for_level_multiplier} of the last
-   * levels extra size. After the data accumulates more so that we need to
-   * move the base level to the third last one, and so on.</p>
-   *
-   * <h2>Example</h2>
-   * <p>For example, assume {@code max_bytes_for_level_multiplier=10},
-   * {@code num_levels=6}, and {@code max_bytes_for_level_base=10MB}.</p>
-   *
-   * <p>Target sizes of level 1 to 5 starts with:</p>
-   * {@code [- - - - 10MB]}
-   * <p>with base level is level. Target sizes of level 1 to 4 are not applicable
-   * because they will not be used.
-   * Until the size of Level 5 grows to more than 10MB, say 11MB, we make
-   * base target to level 4 and now the targets looks like:</p>
-   * {@code [- - - 1.1MB 11MB]}
-   * <p>While data are accumulated, size targets are tuned based on actual data
-   * of level 5. When level 5 has 50MB of data, the target is like:</p>
-   * {@code [- - - 5MB 50MB]}
-   * <p>Until level 5's actual size is more than 100MB, say 101MB. Now if we
-   * keep level 4 to be the base level, its target size needs to be 10.1MB,
-   * which doesn't satisfy the target size range. So now we make level 3
-   * the target size and the target sizes of the levels look like:</p>
-   * {@code [- - 1.01MB 10.1MB 101MB]}
-   * <p>In the same way, while level 5 further grows, all levels' targets grow,
-   * like</p>
-   * {@code [- - 5MB 50MB 500MB]}
-   * <p>Until level 5 exceeds 1000MB and becomes 1001MB, we make level 2 the
-   * base level and make levels' target sizes like this:</p>
-   * {@code [- 1.001MB 10.01MB 100.1MB 1001MB]}
-   * <p>and go on...</p>
-   *
-   * <p>By doing it, we give {@code max_bytes_for_level_multiplier} a priority
