Microservices Architecture: Cross Service data sharing

由 风格不统一 提交于 2020-04-07 10:55:28
问题 Consider the following micro services for an online store project: Users Service keeps account data about the store's users (including first name, last name, email address, etc') Purchase Service keeps track of details about user's purchases. Each service provides a UI for viewing and managing it's relevant entities. The Purchase Service index page lists purchases. Each purchase item should have the following fields: id, full name of purchasing user, purchased item title and price.

android MVP - can I have multiple presenters for custom views and fragments

由 喜你入骨 提交于 2020-04-05 17:45:56
问题 So I have an a presenter that is already tied to an activity. The book says that one presenter should be tied to one view. But now I am adding a few fragments and lots of custom views. I am considering a fragment to be a view as well. The custom views will contain a little bit of logic in them. Both the fragments and custom views are contained in my activity of course. My question is, should I re-use the same presenter in the fragment and custom views or should each view get its own presenter

ServiceStack: Is context based routing specified in the URL possible?

由 折月煮酒 提交于 2020-03-23 02:05:14
问题 I'm looking to retain a ton of functionality I used to have in my codebase from the service layer that I exposed previously using OData services but through ServiceStack, assuming I implement the service logic, I don't want to have to make a ton of new DTO's for requests when this is essentially what i'm trying to achieve unless the framework "forces" me to declare a bunch of extra classes for no functional gain ... [Route("~/{Type}")] public class GetRequest { public string Type {get; set; }

What are microservices? http://microservices.io/ What are microservices? Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of loosely coupled services, which implement business capabilities. The microservice architecture enables the continuous delivery/deployment of large, complex applications. It also enables an organization to evolve its technology stack. Microservices are not a silver bullet The microservice architecture is not a silver bullet. It has several drawbacks. Moreover, when using this

1.4 Camel’s architecture Let’s now turn our attention to Camel’s architecture. We’ll first take a look at the high-level architecture and then drill down into the specific concepts . After you’ve read this section, you should be caught up on the integration lingo and be ready for chapter 2, where we’ll explore Camel’s routing capabilities. 1.4.1 Architecture from 10,000 feet We think that architectures are best viewed first from high above (高空俯视). Figure 1.6 shows a high-level view of the main concepts that make up Camel’s architecture. At a high level, Camel is composed of processors,

iOS simulator on mac is running i386 architecture, not armv7?

由 寵の児 提交于 2020-02-27 04:31:06
问题 I've got some static libraries I've built for use on armv7 architectures. When I try to use them in a iOS project which I testrun on the iphone 5.0 simulator, I get errors telling me about undefined symbols for architecture i386 in my static libraries. So I guess this means the iphone simulator wants libraries compiled for i386? What is the point of the simulator then - why dosn't it emulate armv7 architecture as well? So the only way I can test my static libraries is to connect a physical

What is the best way to process large CSV files?

由 一世执手 提交于 2020-02-20 09:09:29
问题 I have a third party system that generates a large amount of data each day (those are CSV files that are stored on FTP). There are 3 types of files that are being generated: every 15 minutes (2 files). These files are pretty small (~ 2 Mb ) everyday at 5 PM (~ 200 - 300 Mb ) every midnight (this CSV file is about 1 Gb ) Overall the size of 4 CSV s is 1.5 Gb . But we should take into account that some of the files are being generated every 15 minutes. These data should be aggregated also (not
