ThreadLimiter forks threads like Thread.fork(), but limits the
number of concurrently running threads.
ThreadLimiter isn't a thread pool. Each fork really starts a
new thread.
Example: Get the titles of a large collections of URL's.
The traditional way, using Thread directly:
urls = [.....] # A lot of URL's. Maybe
even thousends.
titles =
urls.collect do |url|
Thread.fork do
# ... get the title of the url...
end
end.collect do |thread|
thread.value
end
With ThreadLimiter#fork():
thread_limiter = ThreadLimiter.new(10) # Max. 10 concurrently
running threads.
urls = [.....] # A lot of URL's. Maybe
even thousends.
titles =
urls.collect do |url|
thread_limiter.fork do
# ... get the title of the url...
end
end.collect do |thread|
thread.value
end
With Enumerable#threaded_collect():
urls = [.....] # A lot of URL's. Maybe
even thousends.
titles =
urls.threaded_collect(10) do |url| # Max. 10 concurrently
running threads.
# ... get the title of the url...
end
