python-redis:ConnectionError: Error 32 while writing to socket. Broken pipe?

Question

I want to test the value of redis can support up to 512MB language:python

import redis
conn = redis.Redis()
temp_dict={}
for i in range(1000000):
    temp_dict.update({str(i):str(i)})
conn.hmset('hash-key',temp_dict)

errors: --------------------------------------------------------------------------- ConnectionError Traceback (most recent call last) in () ----> 1 conn.hmset('hash-key',temp_dict)

ConnectionError: Error 104 while writing to socket. Connection reset by peer.

Maybe the data inserted at one time is too large, and the data can be separated and only 100000 pieces can be hmset at a time。

import redis
conn = redis.Redis()

for x in range(10): 
    temp_dict={}
    for i in range(100000):
        temp_dict.update({str(i):str(i)})
    conn.hmset('hash-key',temp_dict)
