Encapsulating Apache Spark for Easy Usage

Xursparks - XAIL's Apache Spark Framework

Overview

Welcome to the Xurpas AI Lab (XAIL) department's Apache Spark Framework. This framework is specifically designed to help XAIL developers implement Extract, Transform, Load (ETL) processes seamlessly and uniformly. Additionally, it includes integration capabilities with the Data Management and Configuration Tool (DMCT) to streamline your data workflows.

Introduction

This framework aims to provide a robust and standardized approach for XAIL developers to handle ETL processes using Apache Spark. By leveraging this framework, you can ensure that your data pipelines are efficient, maintainable, and easily integrable with the DMCT tool.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Apache Spark 3.0 or higher
• Python 3.10 or higher
• Access to the DMCT tool and relevant API keys

Installation

To use framework, follow these steps:

1. install xursparks in python env:

pip install xursparks

2. check if properly installed"

pip list

Usage

Setting Up Your Spark Application To start using the framework, create ETL Job as follows:

import xursparks

xursparks.initialize(args)

ETL Process Implementation

The framework provides predefined templates and utility functions to facilitate your ETL processes.

sourceTables = xursparks.getSourceTables()
sourceDataStorage = sourceTables.get("scheduled_manhours_ELE")
processDate = xursparks.getProcessDate()
sourceDataset = xursparks.loadSourceTable(dataStorage=sourceDataStorage,
												processDate=processDate)

Integration with DMCT

To integrate with the DMCT tool, ensure you have the required configurations set up in your application.properties file:

[default]
usage.logs=<usage logs>
global.config=<dmct global config api>
job.context=<dmct job context api>
api.token="dmct api token"

Best Practices

Always validate your data at each stage of the ETL process.

• Leverage Spark's in-built functions and avoid excessive use of UDFs (User Defined Functions) for better performance.
• Ensure proper error handling and logging to facilitate debugging.
• Keep your ETL jobs modular and maintainable by adhering to the single responsibility principle.

Contributing

We welcome contributions to improve this framework. Please refer to the CONTRIBUTING.md file for guidelines on how to get started.
