concurrent-enum

concurrent-enum is a gem that enhances the Enumerable module with a concurrent_map method, enabling easy concurrent processing of collections.

This is especially useful for I/O-bound tasks, like API calls or database queries, where you want to limit the number of concurrent threads based on your system's capacity or external rate limits.

With concurrent-ruby doing all the heavy lifting, concurrent-enum offers a straightforward way to bring concurrency to Ruby collections.

The # of threads needs to be set manually, as it depends on your particular use case (rate limits, response time, local processing time, etc.).

records = list_of_ids.concurrent_map(max_threads: 10) do |id|
  expensive_api_call(id)
end
