Recently writing a script to check the size of a Redis key value in all of the game area service profiles on a single server was intended to solve this problem by using shell+awk+sed, but because Redis configuration information is in the form of PHP arrays. The shell script was not written in the moment, Ask someone to help write a Python script, but their

I. Introduction of RedisRedis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and hash (hash type). These data types support Push/pop, Add/remove, and intersection-set and difference sets, and richer operations, and these operations are atomic. Based on this, Redis supports sorting in a variety of different ways. A

-max-ziplist-Value: Default value 64activerehashing: The default is yes, to control whether the hash is automatically rebuilt. Active rehashing uses 1 microseconds of CPU time per 100 microseconds to reorganize the Redis hash table. Rebuilding is a lazy way, the more you write a hash table, the more steps you need to perform rehashing, and the rehashing operation will execute if the server is currently idle. If the requirement for real-time is high an

Suppose an application is performing a lpush operation to add a new element to a linked list, and we usually call such a program "producer (Producer)", while another application is performing rpop operations to remove elements from the list, we call this program "consumer (Consumer) "。 If, at this point, the cons

It is a long-lived process, usually independent of the control terminal and periodically performs some sort of task or waits to handle certain occurrences. The daemon is a special orphan process that is out of the terminal and why is it out of the terminal? The reason for leaving the termin
