README

Define ETL pipelines to extract, transform, and load data from one source to another.

Installation

composer require ralphschindler/etl-pipeliner

Usage

To build an ETL pipeline you need the ETL, an Extractor, a Loader and an Executor.

ETL object

Implement a class extending \EtlPipeliner\AbstractEtl. This package ships with an extractor and a loader for use within Laravel application.

class MyEtlObject extends \EtlPipeline\AbstractEtl
{
    public function extractor(): \EtlPipeliner\AbstractExtractor
    {
        return new \EtlPipeliner\Laravel\DbExtractor(app('db')->connection());
    }

    public function transform(array $data)
    {
        return $data;
    }

    public function loader(): \EtlPipeliner\AbstractLoader
    {
            return new \EtlPipeliner\Laravel\DbLoader(app('db')->connection());
    }
}

Execute the ETL

$executor = new \EtlPipeliner\EtlExecutor();

$executor->execute(new MyEtlObject());

Database support

The Laravel extractor and loader currently support:

• Mysql
• SQL Server
• Postgres
