Polling I/O vs Asynchronous I/O
Developers should learn polling I/O for scenarios where simplicity and control are prioritized over efficiency, such as in embedded systems with limited hardware support, real-time applications requiring deterministic timing, or when implementing lightweight protocols in low-resource environments meets developers should learn and use asynchronous i/o when building applications that require high concurrency, such as web servers, real-time systems, or data-intensive processing, to avoid performance bottlenecks from blocking operations. Here's our take.
Polling I/O
Developers should learn polling I/O for scenarios where simplicity and control are prioritized over efficiency, such as in embedded systems with limited hardware support, real-time applications requiring deterministic timing, or when implementing lightweight protocols in low-resource environments
Polling I/O
Nice PickDevelopers should learn polling I/O for scenarios where simplicity and control are prioritized over efficiency, such as in embedded systems with limited hardware support, real-time applications requiring deterministic timing, or when implementing lightweight protocols in low-resource environments
Pros
- +It's useful when dealing with simple devices that lack interrupt capabilities or in educational contexts to understand basic I/O handling, but it's generally avoided in high-performance systems due to its CPU-intensive nature and potential for latency
- +Related to: asynchronous-io, event-driven-programming
Cons
- -Specific tradeoffs depend on your use case
Asynchronous I/O
Developers should learn and use asynchronous I/O when building applications that require high concurrency, such as web servers, real-time systems, or data-intensive processing, to avoid performance bottlenecks from blocking operations
Pros
- +It is essential for handling multiple simultaneous network requests, file operations, or database queries efficiently, as seen in frameworks like Node
- +Related to: event-loop, callbacks
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Polling I/O if: You want it's useful when dealing with simple devices that lack interrupt capabilities or in educational contexts to understand basic i/o handling, but it's generally avoided in high-performance systems due to its cpu-intensive nature and potential for latency and can live with specific tradeoffs depend on your use case.
Use Asynchronous I/O if: You prioritize it is essential for handling multiple simultaneous network requests, file operations, or database queries efficiently, as seen in frameworks like node over what Polling I/O offers.
Developers should learn polling I/O for scenarios where simplicity and control are prioritized over efficiency, such as in embedded systems with limited hardware support, real-time applications requiring deterministic timing, or when implementing lightweight protocols in low-resource environments
