Article Introduction：Unlike Memcache, Redis can persist data to the hard disk. Redis currently provides three persistence methods, RDB, AOF, and RDB-AOF hybrid persistence. Data security and backup are the focus of operation and maintenance work. Let’s take a look at the introduction and application scenarios of RDB persistence.

Article Introduction：1. Introduction to RDB RDB is a method used by Redis for persistence. It writes a snapshot of the data set in the current memory to the disk, which is a Snapshot snapshot (all key-value pair data in the database). During recovery, the snapshot file is read directly into memory. 2. Triggering method RDB has two triggering methods, namely automatic triggering and manual triggering. ①. Automatic triggering: Under SNAPSHOTTING in the redis.conf configuration file, we have introduced it in this article. ①. save: This is used to configure the RDB persistence conditions that trigger Redis, that is, when to save the data in the memory to the hard disk. For example "savemn". Represents the data set within m seconds

Article Introduction：Redis persistence solution Redis is an in-memory database, and data is stored in memory. In order to avoid permanent loss of data due to process exit, the data in Redis needs to be regularly saved from memory to the hard disk in some form (data or commands). When Redis restarts next time, use the persistent file to achieve data recovery. In addition, persistent files can be copied to a remote location for disaster backup purposes. Redis provides multiple different levels of persistence: one is RDB and the other is AOF. RDB persistence can generate a point-in-time snapshot of the data set within a specified time interval, and save the database snapshot to

Article Introduction：Elevator RDB-02 motherboard description? The elevator RDB-02 mainboard is a core component that controls the operation of the elevator. It is based on embedded system design and has high efficiency and reliability. The motherboard supports the control of multiple types of elevators and can achieve different functions through appropriate installation and program settings. The mainboard is also equipped with a variety of protection mechanisms, such as overcurrent, overvoltage, low voltage, leakage, etc., to ensure the safety and stability of the elevator during travel. In short, this motherboard is a must-have solution for elevator manufacturers and maintenance service providers, bringing more convenience and security to the elevator industry. How to check the fault of Xio elevator ncb mainboard? The NCB mainboard of Xio Elevator is the core component of elevator control. When the elevator fails, you need to follow the following steps to troubleshoot: Power supply check: First make sure

Article Introduction：RDB persistence refers to writing a snapshot of the data set in memory to disk within a specified time interval, forking a sub-process, and first writing the data set to a temporary file. After the writing is successful, the previous file is replaced with binary Compressed storage.

Article Introduction：Redis is a non-relational database that is mainly based on memory storage, which makes Redis perform well in scenarios with high concurrency and high read and write speed requirements. However, because Redis stores data in memory, after the server crashes or restarts, the data previously stored in the memory will be cleared and the data will not be persisted, which may cause serious data loss problems. In order to solve this problem, Redis provides a persistence mechanism, mainly using two strategies: RDB and AOF. This article will introduce Redis in detail
