WIP - From 120ms to 30ms: PubNub's Journey to Rust 🦀
From 120ms to 30ms: PubNub's Journey with Rust 🦀
We are thrilled to announce a major milestone in our quest for unparalleled performance: we've achieved a 4x reduction in write latency for our data pipeline, dropping from 120ms to a remarkable 30ms!
This game-changing improvement is the result of a strategic shift to a 100% Rust implementation, replacing our previous C library access by a Python application.
Why the Switch to Rust?
Our data pipeline is a critical component of our real-time communication platform. It handles the task of copying event data from all of our APIs to all our systems. This is powering data processing, storage, connectivity status, and more. While our previous setup using Python and C libraries served us well, we recognized the potential for further optimization.
Enter Rust. Blazing speed, memory safety, and reliability, Rust presented the perfect opportunity to push our data pipeline to new performance heights.
Rust Performance
The switch to Rust delivered exactly what we hoped for:
4x Faster Write Latency: We've significantly reduced the time it takes to write data to our systems, improving overall efficiency and responsiveness.
Improved User Experience: Faster data processing translates to a smoother, more seamless experience for our users.
Enhanced Scalability: Rust's ability to manage resources efficiently allows us to handle even greater volumes of data without compromising performance.
Beyond the Charts
This performance leap goes beyond charts and stats. It's about delivering a better experience for our users and proving how we can drive innovation across our entire platform. By leveraging the power of Rust, we can now focus on pushing the boundaries of what's possible in real-time communication. Many have mentioned a powerful statement in reduction of energy waste. Amazing what Rust can help us with!
Confidence in Rust
This success further solidifies our belief in the potential of Rust in production environments. Its ability to deliver unparalleled performance and reliability makes it an invaluable asset for companies looking to build high-performance applications.
We’ll Keep Deploying New Rust Services
This is just the beginning. We're excited to continue exploring the capabilities of Rust and leverage its power to further optimize our platform. As we continue to innovate and deliver cutting-edge solutions, you can expect even greater performance gains and an even more robust real-time communication experience. Stay tuned for more exciting updates!
