NAME

       AnyEvent::Gearman::Client - Gearman client for AnyEvent application

SYNOPSIS

           use AnyEvent::Gearman::Client;

           # create greaman client
           my $gearman = AnyEvent::Gearman::Client->new(
               job_servers => ['127.0.0.1', '192.168.0.1:123'],
           );

           # start job
           $gearman->add_task(
               $function => $workload,
               on_complete => sub {
                   my $res = $_[1];
               },
               on_fail => sub {
                   # job failed
               },
           );

           # start background job
           $gearman->add_task_bg(
               $function => $workload,
           );

DESCRIPTION

       This is Gearman client module for AnyEvent applications.

SEE ALSO

       Gearman::Client::Async, this module provides same functionality for Danga::Socket
       applications.

METHODS

   new(%options)
       Create gearman client object.

           my $gearman = AnyEvent::Gearman::Client->new(
               job_servers => ['127.0.0.1', '192.168.0.1:123'],
           );

       Available options are:

       job_servers => 'ArrayRef',
           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.

       prefix => 'Str',
           Sets the namespace / prefix for the function names. This is useful for sharing job
           servers between different applications or different instances of the same application
           (different development sandboxes for example).

           The namespace is currently implemented as a simple tab separated concatenation of the
           prefix and the function name.

   add_task($function, $workload, %callbacks)
       Start new job and wait results in %callbacks

           $gearman->add_task(
               $function => $workload,
               on_complete => sub {
                   my $result = $_[1],
               },
               on_fail => sub {
                   # job failled
               },
           );

       $function is a worker function name, and $workload is a data that will be passed to
       worker.

       %callbacks is set of callbacks called by job events. Available callbacks are:

       on_complete => $cb->($self, $result)
           Called when the job is completed. $result is some results data which is set by
           "$job->complete($result)" in worker.

       on_fail => $cb->($self, $reason)
           Called when the job is failed. $reason is empty if its threw by worker. I don't know
           why but gearman spec say so. Considering to use "on_warning" below for some failing
           notify.

       on_warning => $cb->($self, $warning)
           Called when "$job->warning($warning)" called in worker.

       on_data => $cb->($self, $data)
           Called when "$job->data($data)" called in worker.

       on_status => $cb->($self, $numerator, $denominator)
           Called when "$job->status($numerator, $denominator)" called in worker

       on_created => $cb->($self)
           Called when the servers reports that the task was created successfully.  Updates the
           Task object with the server assigned "job_handle".

       You should to set "on_complete" and "on_fail" at least.

   add_task_bg($function, $workload, %callbacks)
       Starts a new background job. The parameters are the same as add_task($function, $workload,
       %callbacks), but the only callback that is called is "on_created".

           $gearman->add_task_bg(
               $function => $workload,
               on_created => sub {
                   my ($task) = @_;
               },
           );
