Validation des messages CDC avec Schemaverse (Partie 4)

Dans cette quatrième partie, nous allons apprendre à valider les messages CDC avec Schemaverse, un outil puissant et facile à utiliser pour la validation des données.

## C’est la partie quatre d’une série de billets de blog sur la construction d’un système moderne à événements avec Memphis.dev.

In this blog post, we will focus on how to use the data captured by Debezium in Memphis.dev to build an event-driven system. We will cover topics such as setting up a data pipeline, creating an event-driven workflow, and deploying the system.

Ceci est la quatrième partie d’une série de billets de blog sur la construction d’un système moderne à événements à l’aide de Memphis.dev.

Dans les deux billets de blog précédents (partie 2 et partie 3), nous avons décrit comment mettre en œuvre une pipeline de capture des données de changement (CDC) pour MongoDB à l’aide de Debezium Server et Memphis.dev.

Dans ce billet de blog, nous nous concentrerons sur la façon d’utiliser les données capturées par Debezium dans Memphis.dev pour construire un système à événements. Nous aborderons des sujets tels que la mise en place d’une pipeline de données, la création d’un flux de travail à événements et le déploiement du système.

Pour commencer, nous devons configurer une pipeline de données pour récupérer les données capturées par Debezium et les envoyer à Memphis.dev. Pour ce faire, nous devons configurer un connecteur Kafka qui envoie les données à un canal Kafka, puis configurer un canal Kafka qui envoie les données à un canal Apache Pulsar. Une fois que la pipeline de données est configurée, nous pouvons commencer à créer des flux de travail à événements basés sur ces données.

Ensuite, nous devons créer un flux de travail à événements qui prend en charge le traitement des données capturées par Debezium. Pour ce faire, nous devons créer un modèle de données qui décrit le schéma des données capturées par Debezium et définir des règles pour le traitement des données. Une fois que le modèle et les règles sont définis, nous pouvons créer un flux de travail à événements qui prend en charge le traitement des données capturées par Debezium.

Enfin, nous devons déployer le système à événements que nous avons construit. Pour ce faire, nous devons déployer le connecteur Kafka et le canal Kafka sur un cluster Kafka, puis déployer le canal Apache Pulsar sur un cluster Pulsar. Une fois que tout est déployé, nous pouvons commencer à envoyer des données capturées par Debezium à notre système à événements et à traiter ces données selon les règles que nous avons définies.

En conclusion, nous avons vu comment utiliser les données capturées par Debezium dans Memphis.dev pour construire un système à événements. Nous avons vu comment configurer une pipeline de données pour récupérer les données capt

Tilda website builder combines everything we liked so much about constructors when we were kids – you can experiment, test out and build myriads of new creative ideas out of ready-to-use blocks. Tilda is that type of constructor that allows you to own your creative process and create pretty much any website: landing page, business website, online store, online course with members area, blog, portfolio, or event promo page.

Founded seven years ago, Tilda is a website builder that completely revamped the way we create websites. Tilda has been the first website builder to introduce block mechanics that allows users to create websites out of pre-designed pieces. This breakthrough technology allowed all users – not only designers – to create professional-looking websites. Just like in kid constructors, you can drag-and-drop and mix-and-match blocks on Tilda to let your creativity flow and build a dazzling website, at extraordinary speed. 

When you ask designers why they love Tilda, they usually say it’s because the platform provides the ultimate balance between choosing from templates and being able to fully customize and create from scratch to bring any creative idea to life. Here’s what else they say:

Tilda has been a game-changer for us. It allows our team to quickly spin up new web pages, make edits, and ship new programs. We left WordPress for Tilda and after being with Tilda for 2 years, I don’t ever want to go back.

~ Andy Page, Executive Director, Forge.

I built my first website in 2001. Since then I’ve used countless platforms and website builders for customer websites and my own business. Tilda is the perfect combination of ease of use with powerful features at an unbeatable value.

~ Robby Fowler, Branding and Marketing Strategist, robbyf.com & The Brand ED Podcast.

Let’s dive deeper into core functionalities you can leverage on Tilda. 

#1 Cut Corners With 550+ Pre-Designed Blocks And 210+ Ready-Made Templates

The beauty of Tilda is that it provides 550+ blocks in the ever-growing Block Library designed by professional designers. Thus, you can quickly build a website out of pre-designed blocks that encompass virtually all elements you might need for your website: menu, about us page, features, contact, pricing, etc. 

Customizing each block is a breeze with Tilda: You can drag-and-drop images, edit text right in the layout, alter block height, background color, padding, select the style of buttons, use custom fonts, and assign ready-made animation effects to specific parts of it. Also, Tilda provides a built-in free image library with 600K+ images, so you can find images that are just right for you without leaving Tilda, add them to your website with just one click, and use them for free.

Finally, all blocks fit together so well that it’s almost impossible to create a bad design on Tilda – even if you are a stranger to website building.

For a quick take-off, you can use 210+ ready-made templates for different kinds of websites and projects: online stores, landing pages, webinar promo pages, multimedia articles, blogs, and more. Each template is a sample of modern web design and consists of blocks. It means that templates don’t limit your creativity: you can modify them to your liking by playing with settings, adding extra or removing existing blocks, and embedding images and text. 

Each of the templates and blocks covers over 90% of use cases you’ll ever require and is mobile-ready, meaning that your website will look great on desktop computers, tablets, and smartphones by default.

#2 Jazz Up Your Site With Zero Block: Professional Editor For Web Designers 

To better meet the demands of a creative brief and unleash your creativity, you can use Tilda’s secret weapon called Zero Block. It is a tool for creating uniquely designed blocks on Tilda.

You can control each element of the block, including text, image, button, or background, and decide on their position, size, and screen resolution on which they’ll appear. For example, you can work with layers to create depth with overlay and opacity techniques or set a transparency level on any element and shadow effects below them. Additionally, you can also insert HTML code to add more complex elements, such as calendars, paywall, comments, social media posts, and so much more.  

Finally, Zero Block allows you to fool around with basic and more advanced step-by-step animation for a more individual look. Here’re some animation examples that you can make on Tilda:

Animation on scroll (position of elements is changing on scroll).

Trigger animation (animation is triggered when pointing at or clicking on an object).

Infinite scrolling text.

#3 Import Designs From Figma To Tilda In Minutes

Creators love using Figma for prototyping, but when you have to transfer every element and rebuild your website design from scratch – that’s what’s killing the party. With Tilda, you can easily turn your static designs into an interactive website in no time. 

All it takes is to prepare your Figma design for import with a few easy steps, paste the Figma API token and your layout URL to Tilda, click import and let the magic happen. Once your design is imported, you can bring your project online just by clicking publish.

#4. Make Search Engines Love Your Website With Built-In SEO Optimization

Thanks to the consecutive positioning of blocks on the page, websites designed on Tilda are automatically indexed well by search engines. There is also a set of SEO parameters you can fine-tune right inside the platform to ensure that your web pages rank high even if you don’t have an SEO specialist in-house. These parameters include the title tag, description and keywords meta tags, reader-friendly URLs, H1, H2, and H3 header tags, alt text for images, and easily customizable social media snippets. 

As an additional value, Tilda provides an SEO Assistant that will show you what errors are affecting the indexing of your website and will help test the website for compliance with the search engines’ main recommendations.

#5. Turn Visitors Into Clients

Tilda gives you the power to set up data capture forms and integrate them with 20+ data capture services, such as Google Sheets, Trello, Notion, Salesforce, Monday.com, etc., to ensure seamless lead generation.

For more fun, Tilda developed its CRM to manage your leads better and keep your business organized right inside of a website builder. This is a very easy-to-use tool that automatically adds leads from forms and allows you to manually add leads you captured outside of the website. There is a kanban board that gives you an overall view of how leads are moving through your sales funnel and allows you to move leads between stages easily.

#6. Build A Powerful Online Store In One Day

Tilda provides a set of convenient features to create a remarkable online shopping experience. The platform gives you the power to sell online using ready-made templates or build an online store completely from scratch, add a shopping cart and connect a payment system of choice — Stripe, PayPal, 2Checkout, etc. — to accept online payments in any currency.

If you are looking to run a large ecommerce business, you should also consider Tilda. Thanks to the built-in Product Catalog, you can add up to 5000 items, import and export products in CSV files, easily manage stock, orders, and keep track of store stats.

And thanks to adaptive design, your store will look good across all devices, including tablets and smartphones. 

#7. Bring Your Project Online For Free

Tilda offers three subscription plans: Free, Personal ($10/month with annual subscription), and Business ($20/month with annual subscription). When you sign up for Tilda, you get a lifetime free account. It allows you to publish a website with a free subdomain and gives you access to a selection of blocks and a limited number of features that offer enough to create an impressive website. 

Personal and Business tariffs allow more advanced options, such as connecting custom domains, adding HTML code, receiving payments, and embedding data collection forms. The business plan also allows users to export their website and create five websites (while personal and free plans allow one website per account). 

To discover all features and templates on Tilda, activate a two-week free trial – no credit card required.

This blog post demonstrates how you can use Change Data Capture to stream database modifications from PostgreSQL to Azure Data Explorer (Kusto) using Apache Kafka.

Change Data Capture (CDC) can be used to track row-level changes in database tables in response to create, update and delete operations. It is a powerful technique, but useful only when there is a way to leverage these events and make them available to other services.

Change Data Capture Architecture Using Debezium, Postgres, and Kafka
was a tutorial on how to use Debezium for change data capture from Azure PostgreSQL and send them to Azure Event Hubs for Kafka – it used the wal2json output plugin.

What About the pgoutput Plugin?

This blog will provide a quick walk through of how to pgoutput plugin. I will not be repeating a lot of details and use containerized versions (using Docker Compose) of Kafka connect, Kafka (and Zookeeper) to keep things simple. So, the only thing you need is Azure PostgreSQL, which you can setup using a variety of options including, the Azure Portal, Azure CLI, Azure PowerShell, ARM template.

Optical Character Recognition (OCR) tools have come a long way since their introduction in the early 1990s. The ability of OCR software to convert different types of documents such as PDFs, files, or images into editable and easily storable format has made corporate tasks effortless. Not only this, it’s ability to decipher a variety of languages and symbols gives Infrrd OCR Scanner an edge over ordinary scanners.

However, building a technology like this isn’t a cakewalk. It requires an understanding of machine learning and computer vision algorithms. The main challenge one can face is identifying each character and word. So in order to tackle this problem we’re listing some of the steps through which building an OCR scanner will become much more clearer. Here we go:
