Harvester Package

This is a large overhaul of the harvester. The focus of this project was to optimize the harvester to avoid extraneous querying and allow que-able processing.

Composer Setup

    "require": {
        "imamuseum/harvester2": ""
    },

Service Provider

In config/app.php add to the autoloaded providers -

Imamuseum\Harvester2\HarvesterServiceProvider::class,

Add ExampleHarvester to app/Providers/AppServiceProvider.php to implement the HarvesterInterface.

    public function register()
    {
        $this->app->bind('Imamuseum\Harvester2\Contracts\HarvesterInterface',
            'Imamuseum\Harvester2\ExampleHarvester');
    }

Now you can publish the package -

php artisan vendor:publish

Push items off the queue Harvester 2 pushes delete jobs onto a queue named "high" and update jobs onto the default queue. This allows the user to define a high and low priority queue to insure delete jobs are run before update jobs.

php artisan queue:listen
php artisan queue:listen --queue=high,low - prioritize "high" queue then "low" queue (or "default" or whatever you name your other queues)

Harvester2 has the flexibility to work with any queue and any document store. At the moment ElasticSearch is the only Document Store that has been implemented. Personally I suggest using Redis as a queue as it plays well with Laravel. If you intend to use sqlite as a queue be sure to use an instance separate from any of your sources (if any of your sources are sqlite databases. The lack of concurrency may cause jobs to fail.

Artisan Commands

php artisan create-index --index=optional - Re-Creates document Store indices according to config. Option to specify which index.
php artisan delete-index --index=optional - Deletes document Store indices according to config. Option to specify which index.
php artisan harvest --source=optional --id=null --recent=false - Runs sync. Option to specify source, id, and whether to pull all or most recently changed data

Use the --help flag after any command to view the available options with a description.
