deprecation judgment made by the current Sentinel instance on a redis server. Objective deprecation: Objectively Down (ODOWN) refers to the interaction between multiple Sentinel instances and the SENTINEL is-Master-down-by-addr commands on the master Server, the Master Server goes offline and starts failover. SDOWNIt is suitable for Master and Slave. As long as a Sentinel finds that the Master enters th

bin, src folder, SRC is the source code, and bin is compiled to execute the file, is also our main use of Dongdong. Into the bin directory, you can see that there are two more directories, one for the 32-bit operating system, and the other for the 64-bit operating system.(4) I am using a 64-bit system, so I will redisbin64.zip copy out, unzip and move to my D:/redis directory, you can see the extracted content contains the following executable EXE fi

, you need to set the password for the primary database through the masterauth parameter in the configuration file of the database, in this way, the AUTH command is automatically used when the slave database is connected to the master database. 3. Naming commandsRedis supports renaming commands in the configuration file. For example, you can rename the FLUSHALL command into a complicated name to ensure that only your applications can use this command

relationship between the slots in the redis cluster and the corresponding nodes in the cluster through communication. the client sends commands to any node in the redis cluster. The Node receiving the Command performs the hash operation and the 16383 remainder operation according to the crc16 rule, and calculates its own slot and corresponding node 3. if the slo

mechanism as a NoSQL database. In Redis, the multi/exec/discard/watch of these four commands is the cornerstone of our implementation of a transaction. I believe that this concept is not unfamiliar to developers with relational database development experience, and even so, we will briefly list In Redis Implementation characteristics of the transaction:1).

(show threads, possibly with SPID column.) The SID column represents the thread ID, and the "CMD" bar displays the thread name. 　　 Warning 2: In the last paragraph of the FAQ, the way to support multithreading starting with the Redis 4.0 version is described, but it's only done on some operations with multithreading! So this article in the future version of whether or not a single-threaded way needs to be verified by the reader! 　　 Six, the attention

Bytes --------------------------------------------------------------------------------------------------- Redis is open-source, BSD Protocol, cache and database in the form of key-value, which is often called a Data Structure server. redis has five data types: String, hash, list, set, ordered Set. Two deployment scenarios of redis: 1. Direct Application access t

not guarantee strong data consistency (strong consistency): Under certain conditions, a Redis cluster may lose a write command that has already been executed.Using asynchronous replication (asynchronous replication) is one of the reasons that a Redis cluster may lose write commands. Consider the following example of a write command:* The client sends a write com

can modify the configuration parameters of the Redis configuration file slave-read-only, modify to No the process of data synchronization ① when an MS relationship is established from the library and the main library, the sync command (Sync command) is sent to the primary database; ② The Home library receives the Sync command and then begins to save the snapshot in the background (the RDB persistence process) and caches the write

, not the incremental synchronization of only dirty data. If the amount of data is large, and more write operations, it will inevitably cause a large number of disk IO operations, may seriously affect performance.In addition, because the snapshot is done at a certain interval, if Redis is accidentally down, all changes after the last snapshot will be lost. You can use AOF persistence if your application requires that you cannot lose any modifications.
