Redis advanced underlying source code 6 – data persistence (RDB method)
1 Overview Redis is an in-memory database. That is, when the server is running, the system allocates a portion of memory to store data. When the service area suddenly goes down, the data in the database will be lost. In order to deal with this situation, persistence must be used. way to save data from […]

Redis RDB persistence
Foreword We know that the reason why Redis is fast is largely because its data is placed directly in the memory, and the memory is a volatile memory. Data is stored only when the power is turned on, and the data will be lost when the power is turned off. At this time, it depends […]

Redis persistent AOF and RDB
Why does Redis need persistence? When thinking about this problem, I think we can think about it in reverse, assuming that Redis does not support persistence, what will be the consequences. First of all, Redis is a memory-based database. Once the Redis service goes down or is restarted, the data in Redis will be lost […]
