利用 redis pipe 极速地向 redis 内插入海量数据：

1、用 python 脚本创建数据：

#!/usr/bin/python
for i in range(100000):
    print 'set name'+str(i),'helloworld'

    # python 1.py > redis_commands.txt

2、用 shell 脚本将这些命令转化成Redis Protocol：

#!/bin/bash

while read CMD; do
  # each command begins with *{number arguments in command}\r\n
  XS=($CMD); printf "*${#XS[@]}\r\n"
  # for each argument, we append ${length}\r\n{argument}\r\n
  for X in $CMD; do printf "\$${#X}\r\n$X\r\n"; done
done < redis_commands.txt

    # sh 20.sh > redis_data.txt

3、写入到 redis pipe

    # cat redis_data.txt > redis-cli --pipe
