What is concurrency in Ruby and how does async I/O work?
Concurrency in Ruby allows multiple tasks to run simultaneously. Async I/O enables non-blocking operations, improving performance.
Can you explain how async I/O differs from traditional I/O?
Sure! Traditional I/O blocks the execution until the operation completes, while async I/O allows other tasks to run during that wait.
What are some libraries in Ruby that support async I/O?
Popular libraries include EventMachine, Async, and Celluloid, which help manage asynchronous tasks effectively.
How can I implement async I/O in a Ruby application?
You can use the Async gem to create tasks that run concurrently. Start by installing the gem and then define your async blocks.
Are there any performance considerations I should be aware of?
Yes, while async I/O can improve performance, it can also introduce complexity. Be mindful of error handling and resource management.
