python mongo异步操作_让python调用mongo读写速度加速10倍的方法

1.把mongo读写封装成api

2.在api初始化时保持数据库长链接；并且用线程每2分钟遍历一次所有的表并count一次

import sys

import time

import pymongo

import json

import log

import traceback

import threading

//库名test，表名test_table

server_list = ['test-mongos.all.serv:6365' for i in range(8)]

conn_str = "mongodb://test:123456@" + ",".join(server_list) + "/test"

print conn_str

conn = pymongo.MongoClient(conn_str)

test = conn.test

def load_cache(){

#load cache

try:

table_names_cache = test.collection_names()

for tb in table_names_cache:

print tb, test[tb].count()

except:

traceback.print_exc()

log.warn("acl data load failed")

# threading reflash

bg_job = threading.Timer(120, load_acl_data,
