Fivetran vs Airflow

Data integration automation tools have revolutionized how businesses handle data management, and among the most prominent options are Fivetran and Airflow. However, choosing a data integration tool that meets your organization’s needs is challenging. Making the correct choice can significantly save your team’s resources, time, cost, and effort.

In this article, let us discuss the key features of Fivetran and Airflow and their differences. The discussion will encompass comparisons based on use cases, flexibility, security, cost, and other relevant factors.

Overview of Fivetran

Fivetran is a modern, cloud-based data movement platform specializing in automating data pipelines. Its wide library of pre-built connectors allows you to streamline the process of extracting, transforming, and loading data between many sources and destinations. Fivetran operates in the ELT (Extract, Load, Transform) format to carry out data integration and helps you integrate with other available cloud-based systems. Additionally, it also allows you to perform complex data management tasks like schema mapping, data transformation, and Change Data Capture (CDC) within a few clicks. 

Key features of Fivetran

• Data movement: Fivetran allows you to efficiently replicate data from over 400+ source connectors to your selected destination. With the help of these connectors, you can access the required data in minutes without writing any codes.‍

Fivetran and Airflow are two different tools that differ broadly in use case, features, and usability. Here are some of the key differences between the tools:

‍

Fivetran Vs Airflow: Use Cases

Fivetran is an ETL tool designed for integrating data from multiple sources to destinations. The primary use case of the platform is to automate the complex process of data pipeline management so you can analyze and access data efficiently. Some of the common use cases of Fivetran include: 

• Seamless integration from various sources to destinations using its wide array of pre-built connectors. 
• Basic data transformation services, including schema standardization, data aggregation, manipulation, filtering, and more.
• Change data capture services for certain connectors to access the most current information for critical analysis. 

On the other hand, Airflow is specifically used for the orchestration of data pipelines. It works with batch pipelines that are a sequence of a bunch of jobs with clear start and end points. However, not being designed for data integration, the platform allows you to integrate data with other systems by expanding its functionality. Here are some of the common use cases of the platform: 

• Orchestration and automating of complex data workflows and pipelines.
• Data migration from source to on-premise or cloud-based destination such as data warehouse, data lake, Snowflake, Redshift, or AWS. 
• Data integration in ETL/ELT formats.
• Automated report generation. 

Fivetran Vs Airflow: Connectors & Operators

Fivetran provides over 300+ pre-built connectors for sources and 14 destination options, including databases, SaaS applications, flat files, and data warehouses. These connectors streamline the process of data extraction and loading from the source to the destination. Being a SasS platform, all the connectors are created and managed by Fivetran's engineering staff. However, it also allows you to create custom connectors for data sources or APIs using Fivetran’s cloud functions. Though it offers a flexible setup and configuration of data pipelines, the flexibility options in this platform are constrained when compared to Airflow.

Since Airflow is not designed to be an ETL tool, it doesn’t have pre-built connectors. However, the platform offers more than 100 operators. Operators are the tools that help orchestrate data pipelines built on other platforms. The operators use Python classes to create a uniform interface for interacting with a wide range of databases, APIs, and cloud services. While Airflow requires more manual configuration and setup, it offers control over data workflows. 

Fivetran Vs Airflow: Customization

Fivetran offers a more streamlined approach using its pre-built connectors and cutting-edge user interface. Most of the operations you perform are pre-defined by the platform. This implies little space for customization, which can be limiting in some cases. For instance, even with a wide library of pre-built connectors, there are cases when the specific source or destination is unavailable on Fivetran. Therefore, it is not an ideal choice for customization. However, Fivetran is well-suited if you are looking for a plug-and-play solution. 

Airflow is designed for flexibility and customization. As an open-source platform, it provides total control over its existing operators and features so that you can tweak them according to your specific business requirements. Airflow also provides a framework for creating custom data workflows and transformation processes using Python scripts. Therefore, developers and engineers can write custom code to define transformation and orchestration logic according to their specific needs. This requires a lot of technical expertise. However, it is ideal for flexible data workflow management needs.
