redis.conf配置文件中：

save 3600 1 300 100 60 10000

 

redis_7007/log/redis-7007.log：

16711:S 16 Feb 2023 10:57:25.708 * 10000 changes in 60 seconds. Saving...
16711:S 16 Feb 2023 10:57:25.709 * Background saving started by pid 20308

16711:S 16 Feb 2023 10:58:48.965 * Background saving started by pid 13522

16711:S 16 Feb 2023 10:58:49.152 * Background saving terminated with success

说明触发了60秒内有10000次的变更，因此需要for一个进程来进行RDB的持久化
