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.

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.

AWS Glue

Rating: 4.2/5 (G2)

Key Features:

  • Centralized metadata management
  • AWS-native and serverless data integration
  • Seamless compatibility with AWS products

thumbnail image

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.

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.

Talend

Rating: 4.0/5 (G2)

Key Features:

  • Open-source platform
  • ELT/ETL
  • 1,000+ connectors for various data sources

thumbnail image

As an open-source ETL solution, Talend provides numerous pre-built connectors and data integration capabilities suitable for on-premises, cloud, or hybrid environments. 

Talend’s ETL capabilities make it a good choice for data warehousing, synchronization, migration, and other data management tasks. Due to its open-source nature, Talend is one of the more technical ETL development tools on this list. If you are planning on empowering your non-technical users to create and manage data pipelines, consider a tool that is easier to use.

Pricing

Talend's Open Studio is available free of charge due to its open-source nature. However, Talend Data Fabric's paid data integration solution's pricing details are private, with some reviewers suggesting the platform may be costly.

The Verdict

Talend is a reliable choice for organizations searching for a robust ETL tool that can integrate with an array of data sources and handle unstructured data. Non-technical users may have challenges using this application due to its complexity, which means technical resources are necessary to create and manage data pipelines.

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. 

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.

How To Evaluate ETL Tools

To ensure you choose the best data integration tool to meet your needs, use the following steps as a starting point:

  • Assess your requirements: Consider your current system requirements, your required integrations, and your team's technical expertise when identifying your data integration needs.
  • Document your must-have features: Opt for platforms that offer user-friendly interfaces, no-code/low-code capabilities, pre-built connectors with the tools you use today, and automation.
  • Review pricing and support: Pick a tool with transparent pricing, considering future needs to the best of your abilities. Make sure the company has detailed documentation, tutorials, and customer support options.  
  • Shortlist and test: Narrow down your options based on your research and take advantage of each platform's free trial to choose the best tool based on your requirements.
  • Select the tool and provide training: Once you’ve selected a platform, provide ongoing training for non-technical users to support them in creating and managing their own data pipelines.

ETL development tools are a powerful addition to any data engineer's toolkit, especially when used to feed machine learning algorithms for data analytics.
