Thread::Pool::Simple - A simple thread-pool implementation

SYNOPSIS

            

              
              
use Thread::Pool::Simple;
my $pool = Thread::Pool::Simple->new(
               min => 3,           # at least 3 workers
               max => 5,           # at most 5 workers
               load => 10,         # increase worker if on average every worker has 10 jobs waiting
               init => [\&init_handle, $arg1, $arg2, ...]   # run before creating worker thread
               pre => [\&pre_handle, $arg1, $arg2, ...]   # run after creating worker thread
               do => [\&do_handle, $arg1, $arg2, ...]     # job handler for each worker
               post => [\&post_handle, $arg1, $arg2, ...] # run before worker threads end
               passid => 1,        # whether to pass the job id as the first argument to the &do_handle
               lifespan => 10000,  # total jobs handled by each worker
             );
my ($id1) = $pool->add(@arg1); # call in list context
my $id2 = $pool->add(@arg2);   # call in scalar conetxt
$pool->add(@arg3)              # call in void context
my @ret = $pool->remove($id1); # get result (block)
my $ret = $pool->remove_nb($id2); # get result (no block)
$pool->cancel($id1);           # cancel the job
$pool->cancel_all();           # cancel all jobs
$pool->join();                 # wait till all jobs are done
$pool->detach();               # don't wait.
            
          

DESCRIPTION

Thread::Pool::Simple provides a simple thread-pool implementaion without external dependencies outside core modules.

Jobs can be submitted to and handled by multi-threaded `workers' managed by the pool.
