Dapper VS Rx.NET

In both samples to get all records and to get a single record works fine but there is a better way to perform the same work using NuGet package Dapper. Dapper is extremely easy to use and built with performance in mind. In the source code provided the basic operations are covered, to take things to the next level and read the information at GitHub, the following page and other code samples in the following repository.

In this article learn how to use Dapper an open-source object-relational mapping (ORM) library for .NET and .NET Core applications. Unlike many articles out there, this one will provide source code to try everything out that is shown in an easy-to-follow way by beginning with a single table then in part two of this series will work with multiple tables.

Dapper

I will be using Dapper - a simple object mapper for .Net along with MySqlConnector.

Maybe the more basic approach to dapper is their documentation https://github.com/DapperLib/Dapper the readme but again most likely you not gonna understand

I think EF Core & EF are the successors to LINQ to SQL that you'd wanna look into, and/or Dapper if you wanna go lower.

The main maintainers of Dapper no longer work at Stack, but they're active enough to comment on recent pull requests: https://github.com/DapperLib/Dapper/pull/1887.

DynamicData is a .NET library that brings the power of reactive programming to collections. It is built upon the principles of Reactive Extensions (Rx), extending these concepts to handle collections like lists and observables more efficiently and flexibly. DynamicData provides a set of tools and extensions that enable developers to manage collections reactively, meaning any changes in the data are automatically and efficiently propagated through the application.

One of the greatest things i discovered recently, is Reactive programming / Reactive Extensions ( https://github.com/dotnet/reactive ).

https://github.com/dotnet/reactive has a lot of different time related extensions for "events". Maybe you'll find something for yourself, if you google for rate limiting with reactive.

Another option is to use the RxJava library in Java. This library uses reactive programming principles to make it easy to write asynchronous and event-driven code. It's particularly well-suited for handling streams of data and allows you to write code that is both efficient and easy to read.

I'd use a dedicated event bus based on Reactive Extensions or MediatR to publish domain events from your domain services. This probably doesn't solve all your ViewModel update problems as is, maybe you need to revise the granularity (maybe you can have smaller ViewModels that refresh single property that exposes the Model) and lifespan (sometimes you can create a ViewModel, make it perform it's task and then discard it completely) of your ViewModels.

If you're finding yourself in a situation where you need to turn this behavior into a pattern because there are a lot of View Models that need to execute async business logic in response to some changes, I'd go with something like MediatR or Reactive Extensions. The idea is, again, that some other, probably business-level, component listens to changes in a decoupled way (that means it doesn't subscribe directly to your View Model, but to an event bus instead). View Model publishes change events to the event bus, and business-component reacts to these events by executing the business logic.
