up the RDB files. An RDB file is a compressed binary file, so the space used is less than the size of the in-memory data and is more advantageous for transmission.
When Redis starts, it automatically reads the RDB snapshot files, loads the data from the hard disk into memory, and depending on the number, the process lasts a different amount of time, typically a record of 10 million string type keys, and a snapshot file size of 1GB takes 20-30 seconds

I. Overview(can skip this paragraph directly) Redis has become more and more widely used as a NoSQL data service, and its greatest advantage over memcached is that it provides a richer data structure, so the application scenario is broader. The advent of Redis is a boon for the vast majority of web application developers, while a large number of open source personnel contribute client-side code, such as the
