High-Performance Data Processing Engine

A high-performance data processing engine written in C++ with a focus on memory efficiency and throughput. The engine implements custom data structures including lock-free queues, arena allocators, and cache-friendly hash maps to minimize allocations and maximize CPU utilization. It processes structured and semi-structured data streams with configurable pipeline stages, supporting both batch and streaming modes. Benchmarks show 3x throughput improvement over baseline implementations for typical observability data workloads. The project includes comprehensive unit and integration tests with sanitizer coverage.
