I have a question about ‘num_levels’ configuration item. If the configuration item ‘num_levels’ is set as 3, will there be [level0, level1, level2], or [level0, level1, level2, level3] levels ? In other words, does the value of ‘num_levels’ here include the [level0] level ?
num_levels includes level0. e.g. num_levels=2 there will be L0 and L1.
