Target of process scheduling: 1, efficiency: High efficiency means that in the same time to complete more tasks. The scheduler is executed frequently, so the scheduler is as efficient as possible. 2, enhance interactive performance (interactivity):

This article explains thread-safety issues about Java member variables, including static and instance variables. Static variables are well understood, all instances share a single memory, and any modification of static variables raises thread-safety

The SSDB configuration file is a hierarchical key-value static configuration file that uses a TAB indent to represent hierarchical relationships. the line starting with # Is a comment. ssdb follows the redis protocol and provides fast read/write

There are two ways for the VM to switch in and out based on value: blocking and multithreading (server. vm_max_threads0 is blocking ). This section describes blocking methods. When redis starts to rebuild the database (aof or snapshot), some values

Communication between different processes requires some identifiers to define the meaning and data format of this communication. These identifiers are often called messages. Next we will discuss how to organize these identifiers and their
