The term “ETL” describes a group of processes used to extract data from one system, transform it, and load it into a target system. A more general phrase is “data pipeline,” which refers to any operation that transfers data from one system to another while potentially transforming it as well.
This blog will introduce you to the basics of both ETL and Data Pipelines and provide their simple applications. It will further provide you with the key difference between these 2 tools that can help you understand the ETL vs. Data Pipeline discussion. Furthermore, it will explain the ideal use cases of both of these technologies. Read along to understand the differences between the Data pipeline and ETL and choose which is best for you!
What is a Data Pipeline?
Data Pipeline acts as the medium using which you can transfer data from the source system or application to the data repository of your choice. The architecture of a Data Pipeline is made up of software tools that collaborate to automate the data transfer process. A Data Pipeline can contain multiple sub-processes, including data extraction, transformation, aggregation, validation, etc. It is an umbrella term for all the data-related processes that can take place during data’s journey from source to destination.
The term “Data Pipeline” can refer to any combination of processes that ultimately transfer data from one location to another. This implies a Data Pipeline doesn’t need to transform the data during its transfer. This differentiates between a ETL vs Data Pipeline which is also a specific type of Data Pipeline. Generally, any of the subprocesses, like Data Replication, Filtering, Transformation, Migrations, etc, can be present in any sequence as part of a Data Pipeline.

What is an ETL Pipeline?
Your organization generates and collects vast data quantities every day. Now, to gather any actionable insight from this enormous sea of data, you will need to:
- Extract and collect data spread across numerous sources that are in some way relevant to your business.
- Perform Data Cleaning and Transformations on the extracted data to make it suitable for Data Analysis.
- Load the transformed datasets into your chosen repository such as a Data Lake or a Data Warehouse and build a single source of truth.
Now, these processes work in a sequence to optimize your raw data into a form that is fit for analysis. However, if you are carrying out the above processes manually, various errors can occur. Your process code may throw sudden errors, certain data values may go missing, data inconsistencies can occur, and many other similar bottlenecks are possible when working with a manual ETL approach.
Businesses rely on an ETL pipeline to automate the three-step task and securely transform their data. An ETL Pipeline is made up of a group of tools that work to extract raw data from different sources, transform & aggregate the raw data and finally load it to your destination storage. A good ETL Pipeline also offers you end-to-end management coupled with an error-handling mechanism.
ETL vs. Data Pipeline: Understanding the Difference
The term Data Pipeline and ETL Pipelines are almost used synonymously among Data Professionals. However, the differences between the Data Pipeline and ETL Pipeline are in terms of their usage, methodology, and importance. You can get a better understanding of the differences between the Data pipeline and the ETL pipeline by comparing the following differences:
A set of procedures known as an ETL pipeline is used to extract data from a source, transform it, and load it into the target system. A data pipeline, on the other hand, is a little larger word that includes ETL as a subset. It consists of a set of tools for processing data transfers from one system to another. However, the data may or may not be transformed.
Using manual scripts and custom code to move data into the warehouse is cumbersome. Changing API endpoints and limits, ad-hoc data preparation, and inconsistent schema makes maintaining such a system nightmare. Hevo’s reliable no-code data pipeline platform enables you to set up zero-maintenance data pipelines that just work.

ETL vs. Data Pipeline: Transformation Process
Data pipelines and ETL pipelines are similar in that they both involve the movement and transformation of data, but there are some key differences between them.
Data pipelines focus on the movement and transformation of data within an organization. They often involve the collection, processing, and storage of data in various systems, such as data lakes or data warehouses. Data pipelines can be used for a variety of purposes, such as data analytics, machine learning, and reporting.
ETL pipelines, on the other hand, are specifically focused on the extraction, transformation, and loading of data from one system to another. ETL pipelines are often used to move data from transactional systems, such as databases, into a data warehouse or data lake for reporting and analysis.
ETL vs. Data Pipeline: How They Run?
The working methodology of data pipelines and ETL pipelines can differ depending on the specific use case and the systems involved. However, in general, data pipelines and ETL pipelines have some key differences in their working methodology.
Data pipelines often involve a continuous flow of data, where new data is collected, processed, and stored in near real-time. This allows for more dynamic and up-to-date analysis and reporting. Data pipelines also often include data quality checks, validation, and error handling to ensure that the data is clean and accurate.
ETL pipelines, on the other hand, are typically run on a schedule, such as daily or weekly. They extract data from transactional systems, transform it to fit the structure and format of the destination system, and then load it into the destination system. ETL pipelines often include more complex transformation processes, such as data mapping, data cleaning, and data deduplication.
In summary, data pipeline are more dynamic and incremental with real-time data movement and processing while ETL pipelines are more batch-oriented, with a schedule of data extraction, transformation and loading.
ETL vs. Data Pipeline: Examples
The following examples are of use cases in ETL vs. Data Pipeline that a Data Pipeline can support but are not achievable via any ETL Pipelines:
- Providing you with real-time reporting services.
- Providing you with the facility to analyze data in real time.
- Allowing you to trigger various other systems to operate different business-related processes.
ETL Pipeline finds applications in various fields depending on their subtasks of Extracting, Transforming, and Loading data. For example, if a company requires data present in different Web Services, Customer Relationship Managers (CRMs), Social Media Platforms, etc., it will deploy an ETL Pipeline and focus on the extraction part.
Similarly, the Data Transformation aspect of an ETL Pipeline is essential for applications that need to modify their data into a reporting-friendly format. Furthermore, Data Loading finds applications in tasks that require you to load vast datasets into a single repository that is accessible to every stakeholder. This implies, that an ETL Pipeline can have a multitude of applications based on its various sub-processes.
Choosing The Right Pipelines for Your Customer Data
Choosing between a data pipeline or an ETL pipeline depends on your specific use case and the systems involved. Both data pipelines and ETL pipelines can be used to move and transform data, but they have different strengths and are optimized for different types of use cases.
In summary, if you are looking to move and transform data within your organization for purposes such as data analytics, machine learning, and reporting, a data pipeline may be a better fit. However, if you are specifically looking to move data from transactional systems, such as databases, into a data warehouse or data lake for reporting and analysis, an ETL pipeline may be a better fit. It’s important to evaluate your specific use case and the resources available to you before making a decision.
