What Is ETL?

ETL stands for Extract, Transform, and Load, which are the three main steps for managing and moving data within a system, typically from multiple sources, into a data warehouse.

ETL is fundamental in data engineering because it facilitates streamlined data management and eliminates common human errors. Data engineers who use ETL processes create more efficient data pipelines to feed their machine-learning algorithm's prediction capabilities.

What Are ETL Development Tools?

ETL development tools are software applications designed to manage the process of extracting, transforming, and loading data from one system to another.

These tools play a critical role in business intelligence, data integration, and data warehousing strategies by helping businesses consolidate data from multiple sources into a unified view for data analysis.

What are the ETL Use Cases for Data Engineering?

There are many ways in which ETL tools are used in data engineering. Here are a few of the most popular real-world examples:

  • Data warehousing: Through ETL, data is extracted from various sources, transformed into a unified format, and stored in a data warehouse, making data analysis tasks more efficient.
  • Data migration: ETL tools facilitate efficient and accurate data transfer between databases and systems with minimal downtime.
  • Real-time data processing: ETL tools enable real-time data processing, which is useful for making quick business decisions.
  • Data cleaning: Using ETL processes, data is identified, corrected, or replicated to ensure high-quality and accurate data for machine learning algorithms.
  • Business intelligence: By integrating data from various sources and loading it into BI tools, ETL tools enable businesses to visualize clean and consistent data in a structured format.

What To Look for in an ETL Development Tool

When evaluating ETL development tools, prioritize your specific requirements and challenges to ensure you choose the tool that aligns with your goals.

Here are some of the most popular factors when deciding on an ETL tool for your business:

  • Integration capabilities: Does the tool support seamless connection with various data sources like the databases, APIs, apps, and other software solutions your organization uses?
  • Ease of use: How does this tool cater to users of all technical proficiency? Does it have a simple user interface?
  • Advanced features: Does the platform support common programming languages like Python, MySQL, and Java?
  • Pricing considerations: Is the vendor's pricing aligned with your current and future needs?
  • Scalability: How well can the platform scale with your business as you grow and your needs change? Can it support more integrations and data without compromising speed and quality?
  • Testimonials and reviews: What are current users of the ETL tool saying about the platform? Are there common themes you can glean through multiple reviews?

Although all ETL tools should meet these fundamental criteria, your specific business needs may require you to consider additional factors.

As a serverless SQL database, AWS Glue from Amazon simplifies data processing tasks for data engineers by facilitating the discovery, cleaning, enrichment, and transfer of data between data warehouses.

AWS Glue eliminates the need for infrastructure and maintenance costs. When setting up a data warehouse, like Amazon Redshift, or data lake, the AWS Glue Catalog is available to help create, monitor, search, and query ETL tasks.

Pros:

  • Serverless: No infrastructure management required.

  • Tight integration with AWS ecosystem: Works seamlessly with S3, Redshift, Athena, and more.

  • Supports PySpark: Offers a powerful transformation engine.

  • Data cataloging: Automatically crawls and catalogs data, making it searchable.

  • Scalable: Handles large volumes of data efficiently.

Cons:

  • Steep learning curve: Especially for non-developers unfamiliar with PySpark or AWS IAM.

  • Debugging is difficult: Logs and error tracing are not intuitive.

  • Slow job startup times: Cold starts can delay pipeline execution.

  • UI limitations: GUI is not as user-friendly compared to other ETL platforms.

Pricing:

Billing for AWS Glue is based on usage; increased tool utilization results in higher costs. You'll be charged hourly for discovering, processing, and loading data. 

A monthly fee does apply to store and access metadata within AWS Glue Catalog. The first million objects stored are free.

The Verdict:

AWS Glue is an excellent solution for companies that are existing AWS customers since it works seamlessly across their ecosystem of tools. The tool offers 70 pre-existing data sources to connect to, which may limit functionality if you use multiple applications and don’t have the technical resources to integrate them properly.

Apache Hadoop

Rating: 4.4/5  (G2)

Key Features:

  • Apache Hive for SQL-like data querying and transformation
  • Apache Pig for scripting complex data transformations
  • Apache Airflow for workflow management
  • Apache Spark for handling real-time data efficiently

Apache Hadoop is not traditionally considered an ETL  tool in the same way that platforms such as Integrate.io, Talend, or Fivetran are. Instead, it's an open-source software library that provides frameworks for distributed storage and processing of large data sets.

However, Hadoop's ecosystem contains tools used in ETL processes. For example, Apache Pig and Apache Hive are used for data transformation, Apache Airflow for workflow management, and Apache Spark for handling real-time data efficiently.

So, while Hadoop is not specifically an ETL tool, it’s a must-have tool for data engineers, especially when dealing with big data

Pros:

  • Highly scalable: Handles petabyte-scale datasets across distributed systems.

  • Open-source: No licensing fees.

  • Ecosystem flexibility: Works with Spark, Hive, Pig, HBase, and others.

  • Good for batch processing: Designed for high-throughput large-scale analytics.

Cons:

  • Complex setup and maintenance: Requires significant operational overhead.

  • Not real-time: Primarily designed for batch processing, not streaming or interactive queries.

  • Steep learning curve: Requires knowledge of HDFS, MapReduce, and related components.

  • Shifting industry adoption: Many teams have moved toward cloud-native or Spark-based alternatives.

Pricing

Apache Hadoop is open source and available to download at no cost.

The Verdict

Apache Hadoop presents a unique offering for data engineers dealing with big data scenarios. Although not a traditional ETL tool like its counterparts, Hadoop's versatile ecosystem and associated applications adapt to various ETL processes. Data engineers who require a scalable and high-performance framework for managing sizable datasets can benefit from incorporating Hadoop into their toolbox.
