Redis批量插入失败，出现奇怪错误

Question

我正在使用管道玩Redis mass import，并拥有以下Python脚本：

mydata = ""
mydata += "*4\r\n$4\r\nHSET\r\n$%d\r\n%s\r\n$%d\r\n%s\r\n$%d\r\n%s\r\n" % (len('myhash'), 'myhash', len('myfield'), 'myfield', len('myvalue'), 'myvalue')

print mydata.rstrip()

它产生：

$ python redis_test.py
*4
$4
HSET
$6
myhash
$7
myfield
$7
myvalue

管道输出：

$ python redis_test.py | redis-cli -h rnode -n 5 --pipe --pipe-timeout 1
All data transferred. Waiting for the last reply...

虽然我让它填充数据库，我想知道是什么导致这些错误？你知道吗

rnode:6379[5]> keys *
1) "myhash"
rnode:6379[5]> hgetall myhash
1) "myfield"
2) "myvalue"

Answer 1

回答我自己的问题：我不知道它需要一个最终的CRLF，因此：

print mydata.rstrip()

成为：

print mydata

结果：

$ python redis_test.py | redis-cli -h rnode -n 5  pipe  pipe-timeout 10
