AnyEvent::Gearman::Worker - Gearman worker for AnyEvent application
use AnyEvent::Gearman::Worker; # create gearman worker my $worker = AnyEvent::Gearman::Worker->new( job_servers => ['127.0.0.1', '192.168.0.1:123'], ); # add worker function $worker->register_function( reverse => sub { my $job = shift; my $res = reverse $job->workload; $job->complete($res); });
This is Gearman worker module for AnyEvent applications.
Create gearman worker object.
my $worker = AnyEvent::Gearman::Worker->new( job_servers => ['127.0.0.1', '192.168.0.1:123'], );
Options are:
List of gearman servers. 'host:port' or just 'host' formats are allowed. In latter case, gearman default port 4730 will be used.
You should set at least one job_server.
Register worker function.
$worker->register_function( reverse => sub { my $job = shift; my $res = reverse $job->workload; $job->complete($res); });
$function_name is function name string to register.
$function_name
$subref is worker CodeRef that will be executed when the worker received a request for this function. And it will be passed a AnyEvent::Gearman::Job object representing the job that has been received by the worker.
$subref
NOTE: Unlike Gearman::Worker, this module ignore $subref's return value. So you should call either $job->complete or $job->fail at least.
$job->complete
$job->fail
This is because this module stands AnyEvent's asynchronous way, and this way more flexible in AnyEvent world.
For example:
$worker->register_function( reverse => sub { my $job = shift; my $t; $t = AnyEvent->timer( after => 10, cb => sub { undef $t; $job->complete('done!'); }, ); });
This is simplest and meaningless codes but you can write worker process with AnyEvent way. This is asynchronous worker.
Unregister worker function, notifying to server that this worker no longer handle $function_name.
