The core behavior is controlled via theasync_insertsetting. When enabled (1), inserts are buffered and only written to disk once one of the flush conditions is met: (1) the buffer reaches a specified size (async_insert_max_data_size) (2) a time threshold elapses (async_insert_busy_time...

但是 asyncio 中的 Queue 实现了 maxsize,当我们想限制流量的时候,这个时候就发挥了作用。如果不需要限流的功能,可以不需要使用 asyncio 中的 Queue。 8. 使用 aiohttp 实现高并发爬虫 # asyncio爬虫.去重.入库 import asyncio import re import aiohttp import aiomysql from pyquery import PyQuery start_url = "...
