We’ve been working on HIGHTITAN—a small, open-source framework designed to handle high-concurrency data streams without the usual overhead of heavy middleware.

The core problem we faced: standard streaming setups were too bloated for our specific low-latency requirements. With HIGHTITAN, we moved to a zero-copy buffer approach, which keeps our processing pipeline extremely lean and fast.

What we’ve learned:

Performance: Achieved stable sub-50ms latency under high load.

Design: Used a minimalist schema definition that avoids unnecessary serialization steps.

If you’re working on real-time data pipelines and want something that stays out of the way, check it out. Would love any feedback on the architecture or ideas on how to optimize the memory management further.
