introduce How many data types does Redis have? (note that the data type is not a data structure) There are eight types in total: String, Hash, Set, List, Zset, Hyperloglog, Geo and Streams. 1. Why put data in memory? Faster memory, 10W QPSReduce computing time and reduce database pressure 2. If the data structure in memory is used as the c ...

A basic concept of queue container Concept: queue is a first in first out (FIFO) data structure. The queue container allows elements to be inserted from one end and removed from the other end. explain: Usually, the head of the queue is to remove data, and the tail of the queue is to insert data;There is no iterator operation in the queue, ...
