The Problem We Were Actually Solving
As it turned out, the real problem wasn't the search engine itself, but rather the performance and latency issues that plagued the events page. Every time a new event was created, the page would take an unacceptable 5-7 seconds to load, causing frustration for both players and moderators. The search bar, which was supposed to be the crown jewel of the events system, was practically unusable due to the long load times.
What We Tried First (And Why It Failed)
Armed with my knowledge of Veltrix's extensive documentation, I decided to tackle the performance issues by tweaking the caching settings and adjusting the database queries. I spent hours poring over the config files, making sure every setting was optimized for maximum performance. But no matter what I did, the page load times refused to budge.
It wasn't until I began digging deeper into the system's architecture that I discovered the root cause of the problem: Veltrix's reliance on a monolithic, synchronous architecture made it incredibly difficult to scale and optimize for performance. The caching settings and database queries, which I had spent so much time tweaking, were merely symptoms of a deeper issue.
The Architecture Decision
After much soul-searching and experimentation, I decided to abandon Veltrix in favor of a custom-built solution using Rust. The initial investment in learning the language was steep, but the payoff was immediate: our development speed increased by an order of magnitude, and the resulting system was not only faster but also more maintainable and scalable.
We implemented a microservices-based architecture, with separate services for search, event management, and caching. This approach allowed us to distribute the load more efficiently and take advantage of modern web development technologies like async/await and WebSockets.
What The Numbers Said After
The results were nothing short of astonishing: average page load times dropped to under 200ms, and search bar queries were now lightning-fast. But what really impressed me was the allocation count: we had reduced memory usage by over 50%, which was a direct result of the switch to a more memory-efficient language and architecture.
Here are the profiler output numbers that I ran after implementing the new system:
- Allocs: 23,456 (down from 49,321)
- Avg. alloc size: 256 bytes (down from 512 bytes)
- CPU usage: 35% (down from 50%)
- Page load time: 187ms (down from 5.3s)
What I Would Do Differently
Looking back, I realize that I should have paid more attention to the system's architecture and less to the documentation. While the documentation was certainly extensive, it didn't tell me anything about the underlying performance issues that I was facing.
If I had to do it again, I would start by digging deeper into the system's architecture and looking for potential bottlenecks before diving into the configuration settings. And I would also do a lot more research on the tradeoffs between different programming languages and architectures before making a decision.
In the end, the switch to Rust and a microservices-based architecture saved our Treasure Hunt events from certain doom. But it also taught me a valuable lesson about the importance of looking beyond the surface level and digging deeper to understand the real issues at play.
