Redis has a flexible extension and gets a double-ended list with a table header complexity of O (1), which is divided into list and listNode2 components.List1typedefstructList {//Linked list2ListNode *head;//Linked list Header3ListNode *tail;//Chain

When it comes to Redis's Dict (dictionary), although the algorithm is no different from the general Dict implementation in the market, there are 2 special places in Redis's dict that is its rehash (re-hash) and its dictionary node one-way list.Here

In fact, this is a pseudo-proposition. As long as Redis is properly compiled, the dynamic library file libhiredis.so is generated in the/deps/hiredis/directory.In order to facilitate the learning of Redis source code, write some test procedures, and

Configuration files based on the redis2.4 version.# Note The unit problem: When you need to set the memory size, you can use a common format like 1k, 5GB, 4M:## 1k = bytes# 1kb = 1024x768 bytes# 1m = 1000000 bytes# 1MB = 1024*1024 bytes# 1g = 1000000

Redis Master-slave replication configuration CombatAfter the actual operation, it is very simple to find the master-slave configuration of Redis:Just write the following two lines of code from the server's redis.conf (example):Slaveof 192.168.1.253 6

The string is the most basic type of redis and can include any type of data, such as a JPG picture or a serialized object.Maximum limit for a single value1 is 1G bytesIf you use only string types, Redis can be seen as a memcache with persistent
