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 Pentaho Data Integration (Kettle)

Pentaho, a subsidiary of Hitachi Vantara, is an open source platform for data integration and analytics. The software comes in a free community edition and a subscription-based enterprise edition. It runs on-premises rather than as a SaaS application.

About Blendo

Blendo is a cloud-based ETL platform.

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

Pentaho Data Integration (Kettle)

Pentaho supports a wide variety of pre- and post-load transformations through dragging and dropping more than two dozen kinds of operations onto its work area. In addition, users can drag and drop custom scripts in Python, Java, JavaScript, and SQL onto the canvas.

Blendo

Blendo focuses on the E and L, extraction and loading, of ELT. It extracts raw data from sources and loads it into destinations without performing transformations.

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.

Pentaho Data Integration (Kettle)

Pentaho can take many file types as input, but it can connect to only two SaaS platforms: Google Analytics and Salesforce. It connects to more than 40 databases, as sources or destinations, via JDBC, ODBC, or plugins.

Blendo

Blendo supports about 50 input data sources, including SaaS platforms and databases. It supports six destinations: Amazon Redshift, Google BigQuery, Microsoft SQL Server, Panoply, PostgreSQL, andSnowflake. Customers can request that the company build a new data source, but no one outside of the company can build new ones or make improvements to existing ones.

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.

Pentaho provides support through a support portal and a community website. Premium support SLAs are available. There's no live support within the application. Documentation is comprehensive. Pentaho provides free and paid training resources, including videos and instructor-led training. A certification program is also available.
