Modern concurrency tools for ruby.
Ruby thread pool gem.
A queue is a basic stack like data structure on which we can call push and pop queue is thread safe so if multiple threads access it at the same time it will maintain consistency.
Thread pools allow you to control the number of active threads at any given time.
A thread pool is an abstraction for re using a limited number of threads to perform concurrent work.

Gem install thread usage pool.
A number of ruby gems exist to support background processing i e saving jobs in a queue and processing them later without blocking the current thread.

Become a contributor and improve the site yourself.

Instantly publish your gems and then install them use the api to find out more about available gems.
For this post i ll use sidekiq and redis an open source key value cache and store.
Gem thread or install it yourself as.

Instantly publish your gems and then install them use the api to find out more about available gems.
Create a queue data structure to represent the set of work that needs to be done.
You can find examples of thread pool implementations in gems like puma concurrent ruby celluloid pmap parallel and ruby thread.
In the following example we are using the celluloid gem to do this for you.
All the implementations i looked at were either buggy or wasted cpu resources for no apparent reason for example used a sleep of 0 01 seconds to then check for readiness and stuff like this.
