Camunda: Basic Auth Performance & Solutions

Hey guys! Let's dive into a crucial topic for Camunda users: basic authentication performance issues. We need to make sure everyone is aware of the potential pitfalls and how to avoid them. This article will cover everything, from identifying the problem to implementing solutions and documenting the process for future reference. So, buckle up and let's get started!

Understanding the Issue: Basic Authentication and Performance Bottlenecks

When we talk about basic authentication in Camunda, we're referring to a simple method where usernames and passwords are sent with each request. While it's easy to set up, basic authentication isn't the most efficient way to handle high loads. Why? Because every single request requires the system to verify the credentials, and that takes time and resources. Imagine checking IDs for every person entering a concert – it works for a small crowd, but for a stadium? You'd need a better system, right? That’s where the performance bottlenecks come in. With a high volume of requests, the constant password checks can lead to CPU spikes and slow response times, essentially crippling your Camunda setup. This is especially critical in production environments where speed and reliability are paramount.

To put it plainly, if you're experiencing slowdowns or your CPU is constantly maxing out, basic authentication might be the culprit. It’s like trying to run a marathon in flip-flops – you can probably do it, but there are much better options available that won’t leave you hobbling. The core issue is that basic authentication only supports a limited number of API requests per second, making it unsuitable for high-load scenarios. This limitation stems from the computational overhead associated with verifying credentials on each request. Each authentication attempt consumes CPU cycles, and when these attempts occur frequently under heavy load, the CPU can become overwhelmed, leading to performance degradation. For smaller applications or development environments, this might not be noticeable. However, in production environments handling a significant volume of business processes and API calls, the impact can be substantial. The symptoms of this issue often include increased response times, application slowdowns, and potentially even service interruptions. It's crucial to recognize these signs early and consider alternative authentication methods to prevent these problems from escalating. This brings us to the critical need for clear documentation and warnings, ensuring that users are aware of these limitations and have the resources to implement more robust solutions. After all, nobody wants their processes grinding to a halt because of a simple authentication method.

Identifying the Problem: Logs and Warnings

The first step in addressing this issue is to make sure users know there is an issue in the first place. That's where application startup logs come in. We need to implement a log that throws a WARNING when basic authentication is configured. Think of it as a friendly heads-up, a flashing light saying,
