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

Funnel

Funnel lets users create preload transformations on dimensions (such as traffic source, media type, and campaign) by specifying rules through a graphical interface. Users can also transform data (such as cost, clicks, and impressions) via rules and formulas.

Elastic Logstash

Logstash provides plugins for several kinds of transformations, including filtering and deserializing data, extracting fields, and enriching data with lookups. Filters are text files, and users can edit existing filters and write their own; Logstash filters are Ruby gems.

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.

Funnel

Funnel claims to support more than 400 marketing and advertising SaaS data sources, and lists more than 275 of them on its site. Destinations include Google BigQuery data warehouse, Amazon S3 and Microsoft Azure Blob Storage data lakes, Google Cloud Storage, and SFTP.

Elastic Logstash

Logstash is a command-line tool that runs under Linux or macOS or in a Docker container. It serves as a way to integrate log data into the Elasticsearch search and analytics service. It supports more than 50 log and event data sources. Destinations include Google BigQuery data warehouse, Google Cloud Storage and Amazon S3 data lakes, Elasticsearch, and more than 50 other file formats and operational monitoring platforms.

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.

Funnel

Funnel provides support via Intercom. Documentation consists of articles in an Intercom knowledge base. Digital training materials are not available.

Elastic Logstash

Logstash vendor Elasticsearch provides support through a customer-only portal. Logstash is also supported through an open source community. Documentation is comprehensive. Digital training materials are not 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.
