Chapter 2 scrapy-redis distributed crawler, Chapter 2 scrapy-redis9-1 Key Points of distributed crawling 1. Advantages of distributed architecture Make full use of the bandwidth of multiple machines to accelerate crawling Make full use of the IP addresses of multiple hosts to accelerate crawling Q: Why does scrapy

REDIS-2.4.15 does not currently provide cluster functionality, Redis's blog says the cluster mechanism will be implemented in 3.0. At present, the method of Redis implementation is mainly to use the consistent ha-sparse slicing (Shard), to assign different keys to different Redis servers, so as to achieve the horizontal expansion. Here's a more common

are some high-cost technical problems that need careful tradeoffs. This series focuses on the service-side caching-related technologies in distributed systems, and also refers to their own thinking details in the context of friends. If there are any irregularities in the text, please correct me.　　The first one tries to talk as much as possible about the underlying design of the cache itself, as well as the

data structure Server software, which provides a distributed data structure storage service based on memory. On implementation, only one thread is used to handle the specific memory data structure, to guarantee the atomic characteristics of its data manipulation commands, it also supports LUA based scripts, each Redis instance uses the same LUA interpreter to interpret the running Lua script, and thus the

Redis is a simple, efficient, distributed, and memory-based cache tool. Assuming that the server is connected over a network (similar to a database), the Key-Value type cache service is provided. 1. what is Redis? Redis is a simpl

first, and after close () calls the Close () method, which is equivalent to generating a new session instance, so we do not have to manually close the session (), It is also not possible to use MyBatis's first-level cache, which means that MyBatis's first-level cache does not work in spring. Therefore, we generally implement the MyBatis level two cache in the pr

PHP distributed cache memcached familiarity and operations, php cache memcached In the era of the rise of the Internet, all major websites are faced with a big data stream problem. How can we increase website access speeds and reduce database operations? As a PHP developer, we can generally think of static page processing, anti-leeching, accelerated access to CDN

not many client connections. you only need to configure entlib as the working method of the shared database partition. All cachemanager instances have read and write permissions on the cache block. Of course, you can also configure to allow only one instance to write, others. There is still no better way, but there are actually some. however, I am surprised that. there is no "Original Ecology" distributed
