Understanding of Modulesmodule, which implements a set of code for a function with a mound code.Like functional programming and process-oriented programming, functional programming accomplishes a function, and other code is used to invoke it, providing reusability of code and coupling between the code. For a complex function, multiple functions may be required to complete (functions can be in different. py files), and the Code collection consisting of N. py files is called a module.such as: OS i

Iv. Factors affecting Redis Performance
*Network bandwidth and latency. It is a good practice to use ping to quickly detect the client and server latency before performing the benchmark test. For bandwidth, it is better to estimate the Gbits/s throughput and compare the theoretical bandwidth value of the network. In many cases, Redis's throughput is limited by the CPU before the network.*CPU is also an importan

Redis has created a new way of storing data. When using redis, we don't have to focus on how to put elephants in the refrigerator in the face of monotonous databases, instead, redis uses flexible data structures and data operations to build different refrigerators for different elephants.

The only way to do this is to make different types of data belong to different applications and separate from each other.So, is there a way for Redis to keep different application data separate from each other and stored on the same instance? is equivalent to the MySQL database, different application data is stored under different databases.Under
