Redis is a high-performance Key-value database with a wide range of applications, similar to memcached, but more powerful!In this paper, according to different functional modules, the configuration parameters of each function module are described in

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

Type settings:The Redis plugin in Logstash specifies three ways to read the information in the Redis queue. List=>blpop ( equivalent to queue ) Channel=>subscribe ( equivalent to a specific channel for publishing subscriptions )

Redis Database The default 16 databases, each database is represented by a REDIS.H/REDISDB structure, the structure of the dict dictionary and Expires dictionary, where dict saved all key value pairs of the library, this dictionary is the key

Implementing Redis's master-slave replication configuration is simple and easy to understand.is the master-slave copy structure that you want to configure:1. DescriptionA master service in Redis master-slave replication can have multiple slave

Redis Collection (SET)Redis's set is an unordered collection of type string. A collection member is unique, which means that duplicate data cannot appear in the collection.The collection in Redis is implemented by a hash table, so the complexity of

Redis lists (list)The Redis list is a simple list of strings, sorted by insertion order. You can add an element to the head of the list (left) or tail (right)A list can contain up to 232-1 elements (4294967295, more than 4 billion elements per list).

Redis Data typesRedis supports five types of data: string (String), hash (hash), list, set (set), and Zset (sorted set: Ordered set).String (String)The string is the most basic type of redis, and you can understand it as a type that is identical to

What is a queue: the simple is that the data is stored in a space (can be memory, or can be a physical file), the first stored data objects, first taken out, which is the opposite of the stack, Message Queuing is also the case of high-concurrency

Now the production environment basically uses the main preparation method, and how to realize the master of Redis? In general, the Redis implementation of master-slave replication is relatively simple, only need to configure the configuration file
