preface Learning notes on Redis underlying integer set (intset). This data type is relatively simple. The main knowledge points are the upgrading of set elements, the search and insertion of elements. In the implementation of element search, the binary search algorithm is used. If you want to learn the implementation of Redis binary sear ...
