我能够在大约15分钟内插入1000万个值。我很高兴速度。我有两个问题：
1）如果我有30倍的数据，我会有任何问题吗？ （约3亿）如果需要，我可以选择增加RAM。
2）我已使用默认的redis安装进行此测试。是否建议配置更改？以下是日志输出......

答案 0 :(得分：5)
如果计划有30倍以上的数据，可以运行“INFO memory”命令，检查used_memory_human的值，乘以30，获取安全边距，看看它是否仍然适合您的服务器。安全裕度取决于Redis实例上应用的写入吞吐量。写的越多，转储时的写时复制开销就越多。
规则是一切都应该适合物理内存。请注意，如果您的服务器还运行其他软件，则需要考虑其内存消耗。运行Redis的服务器永远不应该交换。
关于第二个问题，要更改以定位生产环境的参数不多。我通常只检查日志记录级别（设置它注意）和持久性选项（即存储转储文件的位置等）。
您可能希望在加载数据时停用RDB转储，然后重新激活。您可以使用以下命令从redis-cli执行此操作：
# To deactivate RDB dump
config set save ""
# To reactivate RDB dump (1 dump every 2 hours)
config set save "7200 1"
