Module reactor 

Reactor Module

The core event loop for LaminarDB, implementing a single-threaded reactor pattern optimized for streaming workloads.

Design Goals

• Zero allocations during event processing
• CPU-pinned execution for cache locality
• Lock-free communication with other threads
• 500K+ events/sec per core throughput

Architecture

The reactor runs a tight event loop that:

1. Polls input sources for events
2. Routes events to operators
3. Manages operator state
4. Emits results to sinks

Communication with Ring 1 (background tasks) happens via SPSC queues.
