Our server slowed down. Requests increased. Veltrix failed to scale.
The metrics showed failure.
- Search latency hit 500ms.
- CPU usage stayed above 90%.
- Servers threw connection timeout errors.
We tried to fix the configuration. We changed shards and replication. We added more CPU and memory. These fixes failed.
We treated Veltrix as a black box. We did not understand the internals.
We stopped tweaking. We built a custom search engine using Rust. We wanted full control over the architecture.
The results changed fast.
- Latency dropped to 50ms.
- CPU usage fell to 20%.
- Errors stopped.
Build your own tools when off-the-shelf software fails your needs.
Lessons learned:
- Read the documentation.
- Find the exact bottleneck.
- Weigh the risks of custom builds.
