. Semi-query (only sequential series can be searched) Basic Idea: set N orders (from small to large) to be stored in array a [1] ---- A [n]. The number to be searched is X. Use the variables bot, top, and mid to indicate the bottom (lower-bound array), top (upper-bound array), and center of the data range, mid = (top + BOT)/2, respectively, the half-lookup algorithm is as follows:(1) x = a (MID), the exit l

for scrapy to ensure the speed of crawlers and pipeline. If any of your pipeline throughput is smaller than the throughput of the downloader, this behavior will eventually occur.

All that can be done is to reduce the processing time of pipeline to reduce the number of response objects in
