consultd

consultd is a system daemon designed to facilitate inter-process communication. It acts as a central hub, allowing different applications running on a system to exchange data and signals in a structured manner. At its core, consultd manages a set of named channels or queues. Processes can connect to consultd, subscribe to specific channels, and publish messages to them. This publish-subscribe model decouples the sender from the receiver, meaning applications do not need direct knowledge of each other's existence or location to communicate.

The primary function of consultd is to provide a reliable and efficient messaging layer. It handles the underlying complexities of message routing, buffering, and delivery, ensuring that messages are passed accurately between communicating processes. This can be particularly useful in distributed systems or complex applications where numerous components need to coordinate their activities. Developers can leverage consultd to build more modular and scalable software by abstracting communication logic away from individual application processes. Its design prioritizes low latency and high throughput, making it suitable for real-time data streams and event-driven architectures.
