Flexible availableFor the mass-level distributed service design, we must realize that everything is unreliable, in the environment of unreliable environment to build a reliable application, one of the most important thing is to maintain the flexibility of the system.1. Unreliable environmentWe may have b

systems that can be described are a Markov process .　　But what should we do when the Markov process is not strong enough? In some cases, the Markov process is not enough to describe the pattern we want to discover.　　For example, a reclusive person may not be able to visually observe the weather, but folklore tells us that the state of the algae is associated with weather conditions in some probability. In this case we have two state sets, a set of states that can be observed (the state of the a

In short, familiar with the game environment.9 Every practice game should be as a formal game to do, to ensure that all the questions have been seen, after the game to the non-finished problems as far as possible to fill up.10 if possible, take a look at the summaries, photos and videos of previous competitions, shorte

DSP-based data scheduling strategy for image rotation Algorithms [Date:] Source: Electronic Technology Application Author: Li Linlin, Feng Yan, He Yizheng [Font:Large Medium Small] 　 Image rotation is a widely used digital image processing technology. With the increasing application level, the demand for high-resolution and large image rotation in embedded systems is also increasing. Fo

two records on separate servers, then if there is a business that establishes an "association" for them, it is likely that a record of "association" must be placed in each of the two partitions. In addition, if you value data integrity, transactions across data partitions immediately become performance killers. Finally, if there are some businesses that need to be looked at globally, it is difficult for the data slicing strategy to have any advantage

? Mainly based on the following two points:(1) After setting the global mock switch, it is no longer necessary to set the mock switch for each page, which is easier to maintain, and avoids multiple mock switches in the project and is difficult to unify the switching state;(2) If you forget to turn off the mock switch at the time of release, a running Publisher will notice that the mock switch has been left

Preface:Crawler is a partial IO-type task, the implementation of distributed crawler is more difficult than distributed computing and distributed storage is much simpler.The main points that a distributed crawler should consider are the following: Unified scheduling of Crawler tasks The unified de-weight of crawler tasks Storage issues Speed issues The easier it is to be "robust", the better. It is best to support the "continue crawling" feature Python distribut

In the development of database application based on JDBC, the management of database connection is a difficult problem, because it is an important factor to decide the application performance. Based on a thorough analysis of database connection, this paper proposes and implements an efficient connection management strategy, which makes it relatively easy to devel

Second, policy-based network management The so-called strategy, currently has no uniform standards for its definition and description, according to the IETF de

. * Declarative Transaction model-the most common model, also known as container management transactions. In this model, the container manages the transaction, and the developer defines (declares) the behavior and parameters of the transaction. However, this support can only describe the basic information and expected behavior of the transaction and the syntax and rules used. Transaction policies address the question of when to use required or mandatory attributes, specific directives, which m

work system.Today, I will understand how the Http cache header works together from a system-based perspective (incorrect place, please correct me, but please do not spray me):HTTP Cache ArchitectureFirst I will divide the Http caching system into the following three parts:1. Cache Storage PoliciesUsed to determine whether the Http response content can be cached by the client and which clients can be cachedThis st
