In this blog post, we will see, how we can do a very simple fancy application - Hello World !
In this blog post, let's see how we can download and run Apache HOP (2.9) in Windows 11 environment.
1. Navigate to Apache HOP website. - https://hop.apache.org/
2. Click Download menu option and will navigate to Download page. -https://hop.apache.org/download/
3. Click "apache-hop-client-2.9.0.zip" tod download the Apache HOP client application.
Here are the core keywords used in Apache HOP.
1. Pipelines : A pipelines is set of actions for the transform. It can read the data from the source, process and write the data.
2. HOP: To connect two actions, the HOP will be created.
3. Worflow: It has starting and end points. Majorly consists set of pipelines to execute.
4. Connectors: Connectors are bridges to connect external systems like database, files systems with Apache HOP.
5. Plugins: Plug-ins are prebuilt tools to expand the Apache HOP's capabilities.
Happy Hopping !
What is Apache HOP ?
In simple, Apache HOP is a data engineering and orchestration platform. HOP is abbreviated as Hop Orchestration Platform.
Apache HOP allows users to visually create data pipelines and workflows.
Why we need Apache HOP ?
Apache HOP helps users to automate data extraction from different data sources, performs data cleaning and data transformations and load them into other data sources.

Endpoint Execution filters are new Minimal API in .NET 7 and this feature allows developers to perform validations before the actual API request is executed. The developers can validate the input parameters (from the body/query string or URL template) and validate user authentication information as well.
These validations will make the system more stable and secure as the input parameters are validated before executing the actual code.
There are three types of Endpoint Execution filters are available.
The below blog post helps you to create a new Minimal API project using Visual Studio 2022 in a step-by-step manner.
https://www.codingfreaks.net/2023/01/getting-started-with-minimal-api-first.html
You can use very simple dotnet CLI command to create a plain Minimal API project.
Syntax:
dotnet new web
The above command creates a new Minimal API project with the name HelloWorld.
When you open the project in Visual Studio and it appears like the below.
Step 1: Launch VS 2022 or higher
Step 2: Choose Asp.net Core Web API
Step 3: Click Next and Enter the Project Name, Location name and
Solution Name
Step 4: Choose Framework Version as .NET 7 & the minimum
requirement is .NET 6.
Authentication Type: None
Configure for HTTPS: Yes. Do check the checkbox.
Enable Docker: No. Don’t Check the checkbox
Below are the important to enable Minimal API.
Use Controllers (uncheck to use Minimal API): No (Don’t check
the checkbox)
Enable OpenAPI Support: Yes. Do check the checkbox.
Do not use top-level statements: Yes. Do check the checkbox.
Step 5: Once the application is successfully created, it appears
like the below.
Step 6: Press F5, to run the application.
The Swagger UI page has been launched and you can view the Weatherforecast
API as below.
Step 7: Click on the /weatherforecast API name, click Try it out,
execute and you can see the results as below.
Here is a syntax for creating a new row in the existing, empty collection.
Patch (<CollectionName>, defaults(<CollectionName>), {})
Here is an example of creating a new row in the existing, empty collection.
Patch (Users, defaults(Users), {})
Now, the Users collection will have one empty row and this updated User collection can be used to bind Gallery or datatable in Power Apps.
Happy Coding !
