redis存储方式有哪些

#   In the example below the behaviour will be to save:

#   after 900 sec (15 min) if at least 1 key changed

#   after 300 sec (5 min) if at least 10 keys changed

#   after 60 sec if at least 10000 keys changed

#   Note: you can disable saving completely by commenting out all "save" lines.

#   It is also possible to remove all the previously configured save

#   points by adding a save directive with a single empty string argument

#   like in the following example:

#   save ""

# 持久数据的规则. RDB持久规则. 存储数据的文件由dbfilename参数决定

save 900 1

save 300 10

save 60 10000

# RDB持久数据的文件命名. 可以使用绝对路径配置，如果没有路径配置，在命令运行的相对位置开始寻址存在。
