In the journey of scaling an application, performance issues like slow response times and high latency can sneak up on you. Fortunately, Hazelcast will be useful here.
Read on to find out how.
The Quest for Performance
Diving deep into the bidding app's workings, I encountered the main villain — database interactions were dragging us down. Each bid's journey through the API, service layer, and database was like a marathon with hurdles, where the database challenge was the biggest.
Eager for a solution, I pondered: What if bids didn't have to take this lengthy path? What if they could be processed in a flash, closer to the server? That's when we thought of Hazelcast.
Enter Hazelcast
Hazelcast, an open-source in-memory data grid, promised a way to keep data in memory across clusters, ensuring rapid access and processing. It sounded like the perfect antidote to our performance woes, offering reduced latency, and scalability — all music to a developer's ears.
By the way, Hazelcast isn't just about speed; it's a whole ecosystem offering fault tolerance, scalability, and real-time processing. It's a popular choice for caching in Java apps, known for its prowess in fraud detection, microservices, IoT, and more.
Implementing Hazelcast
Integrating Hazelcast transformed the app's architecture. Bids now bypassed the lengthy database detour, stored temporarily in Hazelcast's nimble in-memory storage. This adjustment didn't just shave milliseconds off the process; it was 20 times faster. The bidding app, once sluggish, was now on a caffeine high, processing bids at lightning speed.
Of course, the "standard" database still played its role, storing and processing bids asynchronously, ensuring no compromise on data integrity.
The Results
Testing the revamped app felt like unveiling a magic trick. The bidding process was not just slightly faster; it could handle 10-20 times more bids per second than before. This wasn't just an improvement; it was a revolution in how the app performed under pressure.
The Takeaway?
This journey with Hazelcast taught me an invaluable lesson: no app is doomed to be slow. With the right tools and a dash of creativity, transforming an app's performance is not just a possibility; it's within reach. Check out this article for more.
