Signal Internals: Managing Memory and the Dependency Graph
The article discusses the importance of memory management and dependency graph management in reactive systems. It explains how a directed graph represents the relationships between signals, computed values, and effects, allowing for precise updates and avoiding redundant computations. Additionally, it addresses the challenges of dangling nodes and stale edges that can lead to memory leaks if not properly managed.
- ▪The Scheduler arranges downstream jobs after data changes but is not sufficient for a stable reactive system.
- ▪A directed graph represents the relationships between signals, computed values, and effects, enabling efficient updates.
- ▪Memory management is crucial to prevent dangling nodes and stale edges that can cause memory leaks.

The Scheduler is responsible for arranging downstream jobs after data changes and batching those updates so the system does not recompute everything immediately and repeatedly. However, scheduling alone is not enough to make a reactive system stable.
