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

mParticle

mParticle lets users track events across multiple applications and send event data to multiple destinations. It's designed to collect and connect customer data from multiple marketing, analytics, and data warehousing tools. It's not primarily an ETL tool, but it does include connectivity to some SaaS data sources and data warehouse destinations. To the extent that it performs ETL operations, mParticle focuses on the E and L, extraction and loading. It extracts raw data from sources and loads it into destinations without allowing users to define their own transformations — though mParticle itself transforms events and objects to conform to its standard as it sends them between different tools, including to the data warehouse. mParticle also lets users create preload transformations in a graphical interface, and write custom rules in JavaScript.

Ab Initio

Ab Initio can perform a wide range of preload transformations through a graphical interface in its Business Rules Environment. The platform bundles several kinds of transformations, and lets users write their own functions in JavaScript or Ab Initio Script.

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.

mParticle

mParticle has a different focus than most ETL tools — it's designed to track events from applications, websites, and mobile apps and unify them into customer profiles. An event is a set of actions that represents a step in the funnel, such as user invited or signed up or order completed. Users can define events that make sense for their business use cases, based on key metrics that provide business value. You embed mParticle tracking into mobile apps or connected devices. The platform creates unique mobile identifiers and tracks things like device IDs, location data, and in-app activity. mParticle supports about 170 destinations, most of which are SaaS platforms for marketing, advertising, and analytics. It also supports data warehouses like Amazon Redshift, Google BigQuery, and Snowflake. Customers can use mParticle's developer tools to track new event sources, but no one outside of the mParticle team or its partners can build new cloud app sources.

Ab Initio

The Ab Initio environment comprises six development and execution components: * Co>Operating System — application development and execution environment * Enterprise Meta>Environment — operational metadata management system * Continuous Flows — dataflow engine for batch and real-time processing * Business Rules Environment and Express>It Web Environment — environment for specifying business rules * Data>Profiler — holistic data quality program * Conduct>It — process automation facility Ab Initio does not publicly disclose how many data sources it supports, but the sources include databases, message queuing infrastructure, and SaaS platforms. Destinations include on-premises data warehouses but no data lakes.

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.

mParticle

mParticle provides support via email. Documentation is comprehensive. Digital training materials are not available.

Ab Initio

Ab Initio provides support via email. Documentation is not publicly available. The company does not provide training materials.

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.
