Parallel Computing Patterns

Patterns that involve running multiple independent tasks concurrently to improve performance.

1. Worker Pool

Limits concurrency by reusing a fixed number of goroutines to process tasks.

2. Queuing

Buffers tasks for controlled, sequential or concurrent processing.

3. Parallel For Loop

Runs loop iterations concurrently using goroutines.

4. Map-Reduce

Distributes tasks across multiple workers and aggregates results.

5. Future (Promise)

Represents a value that will be available at some point in the future, allowing asynchronous computation.

6. Error Group

Runs goroutines in parallel with error handling and cancellation.
