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

dataloader.io

Dataloader.io serves as a tool for centralizing data from files and importing it into Salesforce. It allows users to map fields from CSV files to Salesforce fields, but does no transformation to the data.

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.

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.

dataloader.io

Dataloader.io imports data from CSV files that are stored locally, in Box or Dropbox, or accessed via FTP. There are no tools for writing custom connectors. The platform can export data from Salesforce to the same platforms from which it imports files.

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.

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.

dataloader.io

Dataloader.io provides forum-based support. Professional and Enterprise customers can also get email support. Documentation is comprehensive. No training resources are available.

Attunity

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

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.
