我有一个Web应用程序,每分钟都有数千个请求。 以下是我的mongoDB连接的python代码:
Tool.py:
globalconnection = None
def getCollection(name,safe=False,readpref=ReadPreference.PRIMARY):
global globalconnection
while globalconnection is None:
try:
if not globalconnection is None:
globalconnection.close()
globalconnection = Connection('mongodb://host:port',replicaSet='mysetname',safe=False,read_preference=ReadPreference.PRIMARY,network_timeout=30,max_pool_size=1024)
except Exception as e:
globalconnection = None
request_context.connection = globalconnection
return request_context.connection["mydb"]["mycoll"]
web.py
@app.route("/test")
def test():
request_collection = getCollection("user")
results = request_collection.find()
for result in results:
#do something...
request_collection.save(result)
request_collection.end_request()
一个http请求通过此函数获取连接,
并且http请求在请求结束之前调用end_request。
但我发现在增加请求时,mongoDB中存在许多AutoReconnect错误和超过20000个连接。
你有什么建议吗?

对于自动重新连接,您只需捕获异常,并尝试再次获取连接: http://api.mongodb.org/python/current/api/pymongo/errors.html
30秒的超时时间听起来太长了,请尝试缩短超时时间?
增加mongodb的最大连接数(默认值:20000) http://www.mongodb.org/display/DOCS/Connections
