使用Python3訪問MySQL與Redis，並對二者進行讀寫性能測試

MySQL版本：5.7.28

Redis版本: 3.0.6

Python源代碼:

mysql_insert.py

#!/usr/bin/python3

import pymysql
import time

db = pymysql.connect("localhost","root","tkt","test_db", charset='utf8')

cursor = db.cursor()

try:
   start=time.time()
   db.begin()
   times=0
   for i in range(0, 100000):
       sql="insert into t_student(name,age) values('student_{0}', {0})".format(i)
       cursor.execute(sql)
       times=times+1
   db.commit()
   end=time.time()
   print("mysql insert data spend time: %s(s), times: %d" % (end-start, times))
except:
   db.rollback()

db.close()

mysql_query.py

#!/usr/bin/python3

import pymysql
import time

db = pymysql.connect("localhost", "root", "tkt", "test_db", charset='utf8' )

cursor = db.cursor()

try:
   start=time.time()
   times=0
   for i in range(0, 100000):
       sql = "select * from t_student where name='student_{0}'".format(i)
       cursor.execute(sql)
       times=times+1
   end=time.time()
   print("mysql query data spend time: %s(s), times=%d" % (end-start, times))
except:
   print("Error: unable to fecth data")

db.close()

redis_get.py

#!/usr/bin/python3

import redis
import time

try:
    pool = redis.ConnectionPool(host='127.0.0.1', password = 'tkt', port=6379)
except:
    print("could not connect to redis.")

r = redis.Redis(connection_pool=pool)

start=time.time()
times=0
for i in range(0, 100000):
    value=r.get('key_'+str(i))
    times=times+1
end=time.time()

print("redis get data spend time: %s(s), times: %d" % (end-start, times))

redis_set.py

#!/usr/bin/python3

import redis
import time

try:
    pool = redis.ConnectionPool(host='127.0.0.1', password = 'tkt', port=6379)
except:
    print("could not connect to redis.")

r = redis.Redis(connection_pool=pool)

start=time.time()
times=0
for i in range(0, 100000):
    r.set('key_'+str(i), 'value_'+str(i))
    times=times+1
end=time.time()

print("redis set data spend time: %s(s), times: %d" % (end-start, times))
