redis series 16 persistent RDB
1. Overview Redis is an in-memory database. Once the server process exits, the state of the database memory data in the server will also disappear. In order to solve this problem, Redis provides RDB persistence function, which can save the database state of redis in memory to disk to avoid accidental data loss. RDB persistence […]
Redis RDB persistence
Redis is a key-value pair database server. The server usually contains any number of non-empty databases, and each non-empty database can contain any number of key-value pairs. For convenience, we will list the non-empty databases in the server and their The key-value pairs of are collectively referred to as the database state. For example, the […]
Redis persistent RDB and AOF
Redis persistent RDB and AOF Redis has two persistence schemes, RDB (Redis DataBase) and AOF (Append Only File). If you want to quickly understand and use RDB and AOF, you can skip to the bottom of the article to see the summary. This chapter learns the key knowledge of Redis persistence through configuration files, ways […]
[redis] briefly describe the rdb and aof of redis through the configuration file
There are two persistence methods of redis, rdb, which records the full amount of data on the disk in binary form through snapshots, and aof, which only appends files, and appends incremental write commands to the aof file. When restoring, rdb is faster, but some data will be lost. Aof loses very little data, but […]
Redis persistence (RDB+AOF) and publish subscription
Persistence Redis is an in-memory database. If the in-memory database state is not saved to disk, once the server process exits, the database state in the server will also disappear. Official website address RDB RDB (Redis DataBase Bakup file), redis data backup file, refers to writing the snapshot of the data set in the memory […]
Redis 6.5 RDB and AOF persistent source code
We all know that redis has two persistence methods, one is AOF (Append Only File) and the other is RDB (Redis DataBase). The difference is not introduced here. You can go to Redis Persistence RDB and AOF for comparison and sorting You may have this question, or the interviewer will ask you, when will AOF […]
Java parses Redis rdb files
This program mainly uses java to parse the redis persistent rdb file. Considering that the rdb file may be relatively large and the parsing time is relatively long, it uses one thread to parse and one thread to write to the target file. Each class is explained below: 1. The Common class is mainly used […]
