In this post, we will show how to push Stripe events to Apache Kafka using Upstash Webhook API. Once data is in Kafka there are many use cases how you can use it:

  • Processing payment events (with Apache Flink or Spark) to notify your business and sales team.
  • Trigger processes such as sending Slack messages or email if a payment fails.
  • Using a Kafka connector to move the data to a database or data warehouse to feed reporting and analytics applications.
  • Feeding new payment activity data to your CRM.

In a mobile application, there may be a need to send some information, warnings or guidance to the end-users in the app. One way to do this is sending in-app announcements to the users.

In this blog post, we will develop a mobile application to show how to send announcements to the users with serverless Redis. We will use React Native to develop a mobile application and Upstash for a serverless Redis, which is directly connected to the app.

Nowadays, it is hard to image the IT world without Redis databases. In Stackoverflow's Developer Survey published in 2021, the in-memory database enjoyed great popularity and was chosen as the most loved database by over 70000 developers. As an in-memory database, Redis delivers strong performance, making it ideal in scenarios that require short response times and minimal latency. However, the use cases of Redis are often wrongly understood as being limited to caching and message-brokering. Today we'll look at why this is wrong and use Redis in the role of a primary database.

In this post, we will showcase how to send Github events to Kafka. We will use Vercel functions as a webhook to send events to Upstash Kafka.

You can send all types of repository events to Kafka. We will use Kafka as a persistent hub for our data thanks to its replication and durability capability. Storing Github events in Kafka opens possibilities for both streaming and batching use cases. You can replicate the events to a database for analytical purposes. At the same time, you can run real time processes to trigger alerts for your security team.

As full stack web framework Remix provides APIs to deal with common web server use cases. This post will focus on sessions and why and how you can use Upstash to store them.

What is a session?

The Remix docs have a very good introduction to sessions https://remix.run/docs/en/v1/api/remix#sessions

In a few words - sessions are a mechanism that allows the server and the client to share user data / state. Example of session uses are tracking user authentication state, shopping carts status, flash messages etc.

Remix is a new take on what it means to be a fullstack React framework, focusing on existing web standards and tying the frontend closely to the backend. This tight coupling is a breath of fresh air when you see how simple it is to load data into your React components or how to process data submitted from a form.

In this article we will see Remix's power by creating a simple Feature Flag management system using Upstash Redis as the database.

Logstash is one of the most popular log shipping product that can collect logs from multiple sources and can ship to multiple targets.

In this blogpost, we will ship logs to Upstash Kafka using Logstash. Then we will make simple analysis with Cloudflare Workers. In order to keep the post simple we will ship some sample words from a file but you can ship any logs using Logstash using its input plugins.

Kafka is a messaging and stream processing platform with many use cases. In this post we will talk about the use cases most relevant to web applications.

Website Activity Tracking

You can track your user鈥檚 behaviour on your website using Kafka. You send all types of activities (clicks, searches, scrolls, form submissions) to different Kafka topics. Once you have all activity data in your Kafka, you can consume data to process it for real-time monitoring, real-time processing, and loading to a data warehouse for advanced analytics.
