What is a Data Pipeline? Definition, Types, Best Practices, & Use Cases

Every second, businesses generate massive amounts of data through customer interaction, SaaS applications, and cloud platforms. 

Collecting this data is not a challenge, but the task of connecting data with the systems and the people who need it is. When engineering teams manually parse this data, reports get delayed, and key initiatives fail. 

That is where a data pipeline comes in. 

At the moment data is generated, it relies on automated data pipelines to connect to all systems. Think of it as the circulatory system of any business. It continuously takes data from one system to another (like cloud warehouses, lakehouses, and more). 

Read this guide to learn “what is a data pipeline,” its core components, benefits, types, and more. 

What is a Data Pipeline?

A data pipeline is an automated workflow that moves data from one or more source systems to a destination where it can be stored, processed, or analyzed.

It eliminates the need for manual data extraction. The main purpose of a pipeline is to move the information from one system to another with security and consistency. 

Most of these pipelines include validation capabilities that ensure the data entering the system is accurate and high-quality. 

Typically, a pipeline operates in one of two ways:

• Batch Pipelines: Process large amounts of data at pre-scheduled intervals. 
• Real-Time Pipelines: The data is processed as soon as it is generated. So, it offers nearly real-time updates. 

Data Pipelines

Data pipelines are a broader term. In simple terms, data pipelines refer to the collection of automated workflows a company uses to move and process data. 

It simply means that businesses use more than one pipeline to support their business functions. 

For example, a business may use the following: 

• Customer pipelines
• Sales pipelines
• Marketing analytics pipelines
• IoT pipelines

Each pipeline will serve a different function, data source, transformation logic, and destination. 

Why are Data Pipelines Important?

Data pipelines are crucial because they bridge the gap between raw data and actionable value for a business. Without pipelines, engineers are required to manually extract and clean the data, taking countless hours. 

• Faster Data Processing: Repetitive tasks are automated with data pipelines, resulting in overall faster processing and reduced delays. 
• Better Decision-Making: Timely delivery of data from one system to another enables businesses to make informed decisions. 
• Improved Data Quality: Validation and transformation within the pipelines improve accuracy and consistency. 
• Real-Time Analytics: Real-time pipelines can also support various dashboards, monitoring, and other big applications. 
• Scalability: With pipelines handling all the moving work, it doesn’t become an issue to increase the volume of data. 

How Does a Data Pipeline Work?

In a pipeline, source systems have different methods of processing raw data than target systems. 

Data pipeline software automates the process of extracting data from various sources. Its job also includes transforming, combining, and validating that data for target systems. 

1. Data Collection from Various Sources

A data source can be anything from an application, a device, or another database. The pipeline may extract the data using an API call or a data duplication process. 

2. Data Transformation

When raw data flows through the pipeline, it becomes more useful for business intelligence. Throughout the process, the data is cleaned, validated, and filtered. 

3.  Data Storage 

At the end of the pipeline lies a data warehouse or data lake where it is stored for further use in business. It can also be called a data sink. 

4. Data Consumption

Once the data is stored and processed, it is ready to be consumed by users and analysts. Various applications also use this processed data. 

Data Pipeline Architecture

A modern data pipeline consists of five core components: 

• Sources (from where the data comes)
• Ingestion (moving the data)
• Storage (where it is sent)
• Processing (transforming the data)
• Consumption (analysing or using the data)

Here is a quick breakdown of how essential layers work together in a pipeline. 

• Sources: The starting point from which the data is gathered. All modern architectures can handle structured, semi-structured, and unstructured data. 
• Ingestion: This layer in the data pipeline architecture extracts and transports it from the source to the centralized system. 
• Storage: It can be the place where raw and processed data is stored. The storage locations can include various data warehouses and data lakes. 
• Processing: This layer in the data pipeline cleans, structures, and enriches the data for it to become useful for the business. 
• Consumption: In this stage, the processed data provides value to the business. It can be utilized in analytics, machine learning, & business intelligence. 

Types of Data Pipelines

Not every data pipeline works the same way. How fast data is traveling or how it’s processed depends on the selected architecture. 

There are two main types of pipelines:

• Batch processing
• Streaming 

Let’s check them out in detail. 

Batch Processing

This type of pipeline processes and stores data in large volumes or batches. It is suitable for tasks that require a high volume of data but not immediate accounting. 

As the name suggests, batch processing loads the data into the target system at set intervals. Typically, in non-peak hours of business. Due to this, other workflows of the business are not impacted since batch processing deals with a large amount of data. 

Note: It is the most effective data pipeline method where there is no immediate need to analyze particular data. 

Streaming Data Pipelines

Unlike batch processing, streaming pipelines continue the transfer of data generated by various sources. It is specifically useful for things like sensors or user interactions within an application. 

This type of data pipeline requires low latency. It means the pipeline should be able to handle it even if some packets are lost or received in the wrong order. 

ETL vs. ELT

It is another way to categorize data pipelines when the actual transformation happens. 

Extract, Transform, Load (ETL): This is a traditional approach to handling data. It means the data is extracted from the source, transformed in the middle, and then sent to the target. 

Extract, Load, Transform (ELT): This is slightly different than ETL; here, raw data is extracted and sent directly to the target system. The transformation of the data happens after it reaches the destination. 

Best Practices for Building Efficient Data Pipelines

Building a data pipeline might look easy, but building one that scales and works to correct itself comes with its own set of challenges. 

These practices will help you design efficient pipelines. 

• Design for Scalability: Design a system that has the capability to endure future growth. In the future, the data will change, and the pipeline must change with it. 
• Automate When Possible: Use automation tools to manage tasks and retries whenever possible. Reduce manual intervention to minimize the impact of failures. 
• Validate Data Continuously: Validation will ensure that there are no bad datasets. For that, businesses can build checks for nulls, duplicates, and schema mismatches. 
• Monitor Performance: Track the incoming data for latency, failures, and throughput. 
• Build Modular Pipelines: Try building pipelines into stages that can be independently tested and reused. It will help in isolating failures. 
• Clear Documentation: Maintain clear documentation for sources, transformations, dependencies, and business logic. This will help in easier management and troubleshooting. 

Industries That Use Data Pipelines

Data pipelines are widely used in various industries that serve many purposes. 

Have a look at the common pipeline use cases. 

E-commerce

Big e-commerce platforms like Amazon and eBay gather information about customer interactions that include their purchase history, reviews, and product views. 

After gathering all that data, they feed it to a special algorithm for analysis and generating insights. Ultimately, it will power the personalized marketing campaigns and product recommendations on these platforms. 

Social Media 

Top social media platforms like Facebook and Instagram also leverage data pipelines to collect and analyze user interaction data. This analysis powers their high-performing and secret algorithm to deliver targeted content and advertisements. 

Healthcare

Yes, data pipelines are also used in the healthcare industry. Real-time patient monitoring in the ICU, fetching unified health records, and more can be done in the healthcare sector.
