Article Introduction：I have written articles about RDB persistence and AOF persistence before. They each have their own advantages and disadvantages. RDB files are small in size and fast in loading speed, but they cannot achieve real-time persistence. aof can achieve real-time persistence, but the file size is too large compared to rdb. Is there any way to combine these two methods so that the file size is small and real-time persistence can be achieved? Fortunately, redis supports rdb-aof hybrid persistence since 4.0. And it is the most recommended method now. The configuration is also very simple, only two options need to be configured. appendonly...

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：How to implement form data persistence and persistence layer management in Java? Overview: In web applications, forms are one of the important ways for users to interact with the server. The persistence of form data refers to saving the form data submitted by the user to a database or other persistent storage so that the data can be saved for a long time and accessed by other applications. In Java, various technologies can be used to achieve persistence of form data and persistence layer management. This article will use Java technology as an example to introduce how to achieve persistence and persistence of form data.

Article Introduction：Redis provides two methods for persistence, one is RDB persistence (the principle is to periodically dump Reids' database records in memory to RDB persistence on disk), and the other is AOF (append only file) persistence ( The principle is to write Reids' operation log to the file in an appended manner)

Article Introduction：Redis is an advanced key-value database. It is similar to memcached, but data can be persisted and supports a wide range of data types. There are strings, linked lists, sets and sorted sets. It supports calculating the union, intersection and complement (difference) of sets on the server side, and also supports a variety of sorting functions. Redis supports two persistence mechanisms: RDB and AOF. Persistence can avoid data loss caused by abnormal process exit or downtime. The previous persistence file can be used to achieve data recovery during the next restart. RDB persistence RDB persistence is persisted by creating snapshots (compressed binary files) to save the full amount of data at a certain point in time. RDB persistent

Article Introduction：Redis is an in-memory database. In order to ensure the persistence of data, redis provides two persistence methods, RDB and AOF. Let's take a look at the implementation principles of these two persistence methods respectively.

Article Introduction：There are two kinds of persistence in Redis (AOF and RDB). The following article will take you to understand these two kinds of persistence, look at their advantages and disadvantages, and introduce why Redis needs two kinds of persistence. I hope it will be helpful to everyone. !

Article Introduction：The so-called persistence is to prevent our data from being lost, and the data is usually saved on our hard drive. There are two ways of persistence in Redis, one is snapshot persistence and the other is AOF persistence.

Article Introduction：Redis provides two methods for persistence, RDB persistence and AOF persistence. The principle of RDB is to regularly dump Reids' database records in memory to RDB persistence on disk. The principle of AOF is to write Reids' operation log to the file in an appending manner.

Article Introduction：There are two ways for redis to use RDB persistence. Manual triggering corresponds to the save and bgsave commands respectively; automatic triggering will automatically trigger bgsave when using the save related configuration and execute the shutdown command by default. If the AOF persistence function is not turned on, bgsave will be automatically executed. .
