=head1 NAME

Koha::BackgroundJob::UpdateElasticIndex - Update Elastic index

This is a subclass of Koha::BackgroundJob.

While most background jobs provide a I<process> method, the ES indexing has its
own dedicated worker: misc/workers/es_indexer_daemon.pl

That worker handles all job processing.

=head1 API

=head2 Class methods

=head3 job_type

Define the job type of this job: update_elastic_index

=cut

sub job_type {
    return 'update_elastic_index';
}

=head3 enqueue

Enqueue the new job

=cut

sub enqueue {
    my ( $self, $args ) = @_;

    return unless exists $args->{record_server};
    return unless exists $args->{record_ids};

    my $record_server = $args->{record_server};
    my @record_ids    = @{ $args->{record_ids} };

    # elastic_index queue will be handled by the es_indexer_daemon script

    $self->SUPER::enqueue(
        {
            job_size  => 1,    # Each index is a single job, regardless of the amount of records included
            job_args  => { record_server => $record_server, record_ids => \@record_ids },
            job_queue => 'elastic_index'
        }
    );
