Generating and harnessing data is the top priority for almost every modern business. Regardless of what industry or segment your business is in, there are not many problems that can’t be solved or improved with more data. Of course, data alone is only part of the equation. Being able to move the data into the correct platforms is where the real business value can be derived. 

The data used to generate insights usually comes from various platforms. The data, as it makes its way to the correct downstream platform, passes through a series of processes before it is used for analysis. The whole process of taking raw data, transforming it, and making it available for analysis is facilitated by the data pipeline.

What is a data pipeline?

Data pipelines come in various shapes and forms but all of them have the same goal: to move data from one location and move it to another. Let’s take a deeper look at the definition of a data pipeline.

A data pipeline is a series of actions and processes used to transfer raw data from one point to another.

The term “data pipeline” is now ubiquitous in the world of big data. Data pipelines consist of three key elements: a source, a processing step or steps, and a destination. Looking at each component individually can help one to see exactly how it all comes together. Let’s take a look at all three of the components below:

  • Source: Data source is the place from which data will be extracted. It can be an application database, IoT system, data coming through APIs, data lake or data warehouse, social media data, and public datasets. The data can be structured, unstructured, or semi-structured.
  • Processing: Data processing involves applying transformations to source data to make it ready for analysis. It can be done before or after the data is loaded to the destination.
  • Destination: Destination refers to the final storage location where data will be stored. This could be a big data platform, another application database, or another storage or analytics solution. From there, data can be accessed by other systems for analysis.

Data Pipelines vs Data Warehouses

People who are less familiar with data science terms and tools may get confused as to how data pipelines and warehouses fit together. Both components are used in a modern data stack and play crucial roles within it. Explaining what each component does can help add a lot of clarity.

A data warehouse is a centralized collection of data from multiple sources. A data warehouse provides integrated, time-variant, organized, and non-volatile data. A data warehouse is a one-stop-shop for data. It helps organizations generate insights from data and make efficient decisions. There are many different vendors that supply data warehouse software, most of which have various advantages and disadvantages depending on your use case or familiarity with big data platforms.

In contrast, a data pipeline is a process that extracts data from one system, transforms it, and moves it to another system. A data pipeline can connect data warehouses to other systems and facilitate the movement of data into or out of a data warehouse. A data pipeline is the main mechanism used to move data from a primary location, where the data was collected or stored, to the secondary location where the data will be combined with other data feeds.

Unlike a data warehouse, a data pipeline doesn’t store data. The data pipeline supplied a conduit for data to flow throw without actually storing it. As you can see, both of these components are very closely related when it comes to building out a modern data stack.

Data Pipelines vs ETL process

Another possible point of confusion is the similarities between a data pipeline and an ETL process. In an ETL process, data is extracted from a source, transformed, and loaded to a destination. ETL is a subset of the data pipeline, which is a broader concept. An ETL process is not necessarily a data pipeline, however, some data pipelines can support streaming ETL process capabilities. Let’s discuss the differences between ETL and a data pipeline.

  1. ETL generally works with batch data, that is, data is moved in chunks and it can be scheduled to run at a particular time. In contrast, a data pipeline can work with batch data as well as streaming data. As mentioned, some pipelines can actually support streaming ETL capabilities too.
  2. The destination in ETL is either a database or a data warehouse, while a data pipeline can have multiple destinations such as S3 buckets, data lakes, data warehouses, GCS buckets, or may even initiate a real-time reporting engine.
  3. In the ETL process, a data transformation step is necessary, while in the data pipeline, a transformation step can be skipped depending upon the use case.

Challenges in developing data pipelines

A data pipeline provides a robust solution to move and process data, but developing a data pipeline comes with a few challenges. These challenges impact the quality of data at the destination. Let’s discuss common challenges in developing data pipelines: 

  1. Data is coming from multiple sources and data integration is running in parallel to ingest large volumes of data. This raises issues like non-standardized data, varying type casting, and duplicate data.
  2. Data can be lost during loading due to a power failure or server issues. In most scenarios, data is recovered, but it can be challenging and difficult to identify which can lead to missing or duplicate data in the target.
  3. The data pipeline must be flexible to incorporate changes happening in the source system where data is coming from.
  4. Selecting the right tools and technologies to design data pipelines is important. There are many options available, but selecting the right tool depends upon the use case and budget for the project.

Types of Data Pipeline Tools

Data pipeline tools can be divided into different categories based on the use case. Let’s explore different types of data pipeline tools.

Open-Source vs Private Data Pipeline Tools

Open-source tools are made publicly available and can be customized by users. These tools are usually free, but to enhance their functionality, expert developers are required or an enterprise license is required to unlock some features. Open-source tools include:

  • Airbyte
  • Apache Kafka
  • Talend

On the other hand, private/closed-source data pipeline tools cater to specific business use cases and are fully managed. These tools offer state-of-the-art solutions for data pipelines and don’t require customization. Private data pipeline tools include:

  • Arcion
  • Hevo Data
  • Stitch
  • Fivetran

On-premises vs Cloud-native data pipeline tools

Due to security and data privacy constraints, many businesses, especially those in highly-regulated industries, have on-premise systems to store their data. Sometimes, these companies also require on-premise data pipeline tools as well. The main reason for deploying on-premise data pipeline tools instead of those based in the cloud is to provide better security and control. On-premise tools include:

  • SAP
  • Informatica
  • Oracle Data Integrator

Cloud-native data pipeline tools make use of the cloud to transfer and process data. By using the power of the cloud, these tools can sometimes be more scalable and cost-efficient than running data pipelines on-premise. Many provide extremely secure infrastructure to store data contrary to the popular belief that cloud deployments are less secure than on-premise ones. Available cloud-native tools include:

  • Equalum
  • AWS DMS
  • Hevo Data

Batch vs Realtime Data Pipeline Tools

Batch Data Pipeline Tools move data in chunks or batches in intervals. These tools don’t support real-time data processing and tend to be considered a more legacy approach to moving data. Batch data pipeline tools include:

  • Talend
  • IBM InfoSphere DataStage
  • Informatica PowerCenter

Real-time data pipeline tools perform ETL on data and deliver the results for decision-making in real time. Data is ingested from streaming sources such as IoT devices and sensors in self-driving cars. Most processes that are using AI and ML to power business decisions or predict consumer/user behavior will use these types of data pipelines. Real-time data pipeline tools include:

  • StreamSets
  • Hevo Data
  • Confluent

Factors that Drive Data Pipeline Tool Decisions

Data pipeline tools help with extracting data from a data source, applying data transformations, and moving the data into one or multiple data storage locations. There are tools available to carry out each step in the data pipeline process and many tools cover every aspect of it. The decision to choose the right tool can be overwhelming, but with the right insight, it doesn’t have to be. Let’s look at the factors that you should consider when selecting data pipeline tools:

  1. Type of Data: The data pipeline tool you decide on may depend upon the type of data that’s going to be ingested by the pipeline. Is it real-time or batch data? 
  2. Data Size: The amount of data that you will be transporting can determine which tools may be best suited for your use case. How much data will be processed in a single run? In the case of large data sets, how much time does the tool take to process the amount of data you’ll be moving? 
  3. Data Transfer Frequency: The frequency in which data transfer will be happening should also be of consideration. In the case of batch data, how often should the pipeline run?
  4. Data Quality: Does the tool support data quality checks and how will they be applied to ensure good data quality? Data quality is an important aspect of data pipelines.
  5. Cloud support: If needed, the data pipeline tool chosen should provide multi-cloud support. Multi-cloud support means data tools can move data between different clouds and can work with data residing on different cloud platforms. Cloud and multi-cloud support can be important for those looking for cloud-based solutions.
  6. Data Transformation: How is data transformation done? Do you require the data to be processed quickly? What’s the processing time the data tool should take?
  7. Cost: Costs can vary heavily between tools or even depending on license requirements. Be sure to know the amount of data you will be moving and how quickly that data needs to be moved, in order to calculate potential infrastructure license costs as well. Although free tools are available, paid tools are generally required for production or large-scale operations.
  8. Data sources and destinations: How many data sources and destinations are supported by your tool of choice? Do the tools supported technologies work with your current architecture and your future-state roadmap? Data source refers to the location from where data will be extracted, and data destination refers to the place it will be stored.
  9. Customer Support: Does the tool offer customer support? Customer support can help users to utilize the tool efficiently and help with any configuration or runtime errors that are experienced. Having multiple channels of support generally leads to a better experience.
