Producer-Consumer Problem
The Producer-Consumer problem is a synchronization problem in concurrent computing where:
- Producers create data items and place them in a shared buffer
- Consumers remove and process these items from the buffer
The system must ensure:
- Producers don't add to a full buffer
- Consumers don't remove from an empty buffer
- No data corruption from simultaneous access to the buffer
This problem demonstrates the need for synchronization mechanisms like semaphores, monitors, or concurrent data structures in multi-threaded environments. Solutions must handle race conditions, deadlocks, and resource constraints while maintaining throughput.
Types:
- SPSC: Single Producer, Single Consumer
- MPSC: Multiple Producers, Single Consumer
- SPMC: Single Producer, Multiple Consumers
- MPMC: Multiple Producers, Multiple Consumers
