What Is a Secondary Index?

secondary index just points back to the primary key that's used, or at least an example that they gave here under your mind. If you don't have that index, yuve got to read the whole book every time you want to find it? Yes! The author really got into like, the underlying storage mechanism for this particular case of the secondaryIndex. So i was just assuming that it wouldyw stay consistent with that, yet kept it really basic. An this whole of the chapter is really kind of bias towards no sequel, i thought.
