Redis Default persistence method RDB What are the advantages ？

Take the answer 1：

1、 Only one file dump.rdb, Easy persistence .

2、 Good disaster tolerance , A file can be saved to a safe disk .

3、 Maximize performance ,fork Sub process to complete the write operation , Let the main process continue processing commands , So it is IO Maximize . Use a single child process for persistence , The main process will not do anything IO operation , To ensure the redis A high performance
