Most businesses have data stored in a variety of locations, from in-house databases to SaaS platforms. To get a full picture of their finances and operations, they pull data from all those sources into a data warehouse or data lake and run analytics against it. But they don't want to build and maintain their own data pipelines.

Fortunately, it’s not necessary to code everything in-house. Here's an comparison of two such tools, head to head.

About Adverity Datatap

Adverity is a marketing data analytics platform with products that address data integration, data visualization, and augmented analytics. Datatap, the data integration module, handles ETL processing for many sources specifically of interest to marketing organizations.

About Apache Airflow

Apache Airflow is an open source project that lets developers orchestrate workflows to extract, transform, load, and store data.

About Stitch

Stitch Data Loader is a cloud-based platform for ETL — extract, transform, and load. More than 3,000 companies use Stitch to move billions of records every day from SaaS applications and databases into data warehouses and data lakes, where it can be analyzed with BI tools. Stitch is a Talend company and is part of the Talend Data Fabric.

Let's dive into some of the details of each platform.

Transformations

Adverity Datatap

Adverity Datatap provides pre-load transformations through scripts, which can be configured through online forms or by editing code. Custom scripting, using Adverity's scripting language, allows users to write their own transformations.

Apache Airflow

Apache Airflow is a powerful tool for authoring, scheduling, and monitoring workflows as directed acyclic graphs (DAG) of tasks. A DAG is a topological representation of the way data flows within a system. Airflow manages execution dependencies among jobs (known as operators in Airflow parlance) in the DAG, and programmatically handles job failures, retries, and alerting. Developers can write Python code to transform data as an action in a workflow.

Stitch

Stitch is an ELT product. Within the pipeline, Stitch does only transformations that are required for compatibility with the destination, such as translating data types or denesting data when relevant. Stitch is part of Talend, which also provides tools for transforming data either within the data warehouse or via external processing engines such as Spark and MapReduce. Transformations can be defined in SQL, Python, Java, or via graphical user interface.

Connectors: Data sources and destinations

Each of these tools supports a variety of data sources and destinations.

Adverity Datatap

Adverity Datatap supports more than 200 database and SaaS data sources. It can write data to cloud data warehouses and cloud data lakes as well as MySQL and PostgreSQL databases and Hadoop.

Apache Airflow

Airflow orchestrates workflows to extract, transform, load, and store data. It run <b>tasks</b>, which are sets of activities, via <b>operators</b>, which are templates for tasks that can by Python functions or external scripts. Developers can create operators for any source or destination. In addition, Airflow supports plugins that implement operators and <b>hooks</b> — interfaces to external platforms. The Airflow community has built plugins for databases like MySQL and Microsoft SQL Server and SaaS platforms such as Salesforce, Stripe, and Facebook Ads.

Stitch

Stitch supports more than 100 database and SaaS integrationsas data sources, and eight data warehouse and data lake destinations. Customers can contract with Stitch to build new sources, and anyone can add a new source to Stitch by developing it according to the standards laid out in Singer, an open source toolkit for writing scripts that move data. Singer integrations can be run independently, regardless of whether the user is a Stitch customer. Running Singer integrations on Stitch’s platform allows users to take advantage of Stitch's monitoring, scheduling, credential management, and autoscaling features.

Support, documentation, and training

Data integration tools can be complex, so vendors offer several ways to help their customers. Online documentation is the first resource users often turn to, and support teams can answer questions that aren't covered in the docs. Vendors of the more complicated tools may also offer training services.

Adverity Datatap

Adverity provides support through an online ticketing system. Documentation consists largely of tutorials. The company does not provide training materials or services.

Apache Airflow

The open source community provides Airflow support through a Slack community. Documentation includes quick start and how-to guides. Other than a tutorial on the Apache website there are no training resources.

Stitch

Stitch provides in-app chat support to all customers, and phone support is available for Enterprise customers. Support SLAs are available. Documentation is comprehensive and is open source — anyone can contribute additions and improvements or repurpose the content. Stitch does not provide training services.

Pricing

Adverity Datatap

Adverity Datatap pricing depends on the number of data sources a company integrates, the number of accounts that connect to those data sources, and how the data will be used.

Apache Airflow

Airflow is free and open source, licensed under Apache License 2.0.
