Spread::Queue::Manager - coordinate one-of-many message delivery
The provided 'sqm' executable does this:
use Spread::Queue::Manager; my $queue_name = shift @ARGV || die "usage: sqm queue-name"; my $session = new Spread::Queue::Manager($queue_name); $session->run;
The queue manager is responsible for assigning incoming messages (see Spread::Queue::Sender) to registered workers (see Spread::Queue::Worker).
When a message comes in, it is assigned to the first available worker, otherwise it is put into a FIFO queue.
When a worker reports availability, it is sent the first pending message, otherwise it is put into a FIFO queue.
When a message is sent to a worker, the worker should immediately acknowledge receipt. If the worker does not acknowledge, the message will (eventually) be assigned to another worker.
If a queue manager is already running (detected via Spread group membership messages), the new sqm should terminate.
my $session = new Spread::Queue::Manager($queue_name);
Initialize Spread messaging environment, and prepare to act as the queue manager. If queue_name is omitted, environment variable SPREAD_QUEUE will be checked.
Run loop for the queue manager. Does not return unless interrupted.
