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 build everything in-house. We put together this ETL tool comparison guide to help you choose the product that’s the best fit for your business.

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

Transformations

Attunity

Attunity supports 10 types of simple pre-load global transformations, such as renaming tables and schemas, adding and dropping columns, and converting data types. Users can also build transformations through an Expression Builder graphical interface using SQLite operators and functions.

Matillion

Matillion supports post-load transformations through what it calls Transformation Components. Users can create Transformation Components via point and click selection or by writing them in SQL. Components may be dragged onto Matillion's visual workspace at an appropriate spot in the data pipeline.

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.

Attunity

Attunity offers several products: Replicate for data replication, Compose for data ingestion, Enterprise Manager for managing Replicate and Compose tasks, and Gold Client for test data management in SAP environments. Attunity Replicate runs on a Windows or Linux server, and supports about 30 database and file data sources. The software focuses on high-volume and low-latency database replication scenarios, including streaming near-real-time updates. It supports a variety of destinations: cloud data warehouses and data lakes, on-premises data warehouses, flat files, and streaming services. Attunity Compose, which can integrate with Attunity Replicate, comes in two editions, for automating the building of data pipelines to on-premises data lakes and data warehouse.

Matillion

Matillion integrates with about 60 data sources in seven categories: CRM and marketing communications, ERP, finance, social networks, databases, document and file formats, and internet resources. Customers can request that the company build a new data source, but no one outside of the company can build new data sources or make improvements to existing sources. It supports Redshift, BigQuery, and Snowflake destinations.

Stitch

Stitch supports more than 100 database and SaaS integrations as 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.

Attunity

Attunity provides online, email, and telephone support. Documentation is comprehensive. Digital training materials and on-site classes are available.

Matillion

Matillion provides support through an online ticketing system accessible through a support portal or via email. Documentation relies on articles accessible through the support portal. The company doesn't provide training services, but tutorial videos are available on the company's YouTube channel.

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.
