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 Google Cloud Dataflow

Google Cloud Dataflow lets users ingest, process, and analyze fluctuating volumes of real-time data. It's one of several Google data analytics services, including:

Stitch and Talend partner with Google. While this page details our products that have some overlapping functionality and the differences between them, we're more complementary than we are competitive. Google offers lots of products beyond those mentioned here, and we have thousands of customers who successfully use our solutions together.

About Dell Boomi

Boomi implements cloud-based application integration using a graphical front-end interface. The company was acquired by Dell in 2010.

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

Google Cloud Dataflow

Cloud Dataflow provides a serverless architecture that can shard and process large batch datasets or high-volume data streams. The software supports any kind of transformation via Java and Python APIs with the Apache Beam SDK.

Dell Boomi

Boomi handles process execution through procedures it calls shapes. Boomi supports a set of prebuilt transformations within its various shapes (such as text encoding, encryption/decryption, search/replace, and combining documents), and it lets users create custom preload transformations by coding JavaScript or Groovy scripts to convert data from the source application into a format that can be used by the destination.

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.

Google Cloud Dataflow

Cloud Dataflow supports both batch and streaming ingestion. For batch, it can access both GCP-hosted and on-premises databases. For streaming, it uses PubSub. Cloud Dataflow doesn't support any SaaS data sources. It can write data to Google Cloud Storage or BigQuery.

Dell Boomi

Like other application integration platforms, Boomi typically replicates data changes one at a time between multiple systems, as events happen, rather than pushing batches of data to a single central repository. Boomi supports two kinds of connectors, which it calls application and technology connectors. There are 80 application connectors (mostly to SaaS platforms, including data warehouses and data lakes) and 22 technology connectors (to databases and services like SFTP, HTTP, and IMAP). Developers can write their own custom connectors in Java using Boomi's Connector SDK.

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.

Google Cloud Dataflow

Google provides several support plans for Google Cloud Platform, which Cloud Dataflow is part of. Documentation is comprehensive. Google offers both digital and in-person training.

Dell Boomi

All customers get email support, and customers on premier support plans get live chat and phone support. Dell also offers Boomi consulting, including onsite consulting for support. Documentation on Dell's help site is comprehensive. A community site provides additional peer and company support. Dell offers on-demand and instructor-led digital training.

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.
