Overview
The pool package manages a finite set of reusable resources, enabling efficient control over concurrent operations such as file system access or network requests. By limiting the number of simultaneous tasks, it helps prevent resource exhaustion and improves performance in I/O-intensive applications. It provides a simple API for acquiring and releasing resources from a shared pool, ensuring safe and predictable concurrency. Ideal for scenarios requiring throttled execution of async operations.
Use cases
- Limiting concurrent HTTP requests
- Controlling file I/O operations
- Managing database connections
- Throttling background tasks
- Optimizing resource usage in web apps
- Handling high-volume data processing
Key features
- Finite resource pooling
- Automatic resource management
- Simple async acquisition
- Supports concurrent task throttling
- Built-in error handling
- Lightweight and reliable
Suitable for
- Apps with heavy I/O operations
- Network-heavy services
- File processing pipelines
- High-concurrency environments
- Dart CLI tools
- Server-side Dart applications
Considerations
- Requires careful sizing of pool capacity
- Does not handle resource cleanup automatically
- Not suitable for long-lived stateful resources
- Best used with async/await patterns
- Limited to synchronous resource types
- Needs proper error handling in client code
