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.

Overview

StreamSets, AWS Glue, and Stitch are all popular platforms. Here's a side-by-side look at how they stack up against each other.

Focus ETL, transformations, data prep ETL, data catalog Data ingestion, ELT
Database replication Full replication or change data capture Full table; incremental via change data capture through AWS Database Migration Service (DMS) Full table; incremental via change data capture or SELECT/replication keys
SaaS sources Only Salesforce None More than 100
Ability for customers to add new data sources Yes Developers can write custom Scala or Python code and import custom libraries and Jar files into Glue ETL jobs to access data sources not natively supported by AWS Glue. Yes

Data sharing No Yes, within AWS Yes, through Talend Data Fabric
Vendor lock-in Annual contracts. StreamSets Data Collector is open source, other parts of the platform are proprietary. AWS Glue is strongly tied to the AWS platform. Usage is billed monthly. Month to month or annual contracts. Open source integrations

Let's dive into some of the details of each platform.

Transformations

StreamSets

StreamSets comes with more than 50 pre-load transformation processors, which users can drag and drop onto a graphical workspace. Processors can look up, remove, convert, parse, and aggregate data from various sources. Developers can write their own custom processors in Java, Java Expression Language (EL), JavaScript, Jython, Groovy, and Scala.

AWS Glue

AWS Glue provides 16 built-in preload transformations that let ETL jobs modify data to match the target schema. Glue generates Python code for ETL jobs that developers can modify to create more complex transformations, or they can use code written outside of Glue.

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.

StreamSets

The StreamSets DataOps Platform includes five components:

  • Control Hub is the dashboard for building, deploying, and operating data flows.
  • Data Collector is an open source tool for designing streaming data pipelines with both a graphical UI and a command-line interface.
  • Data Collector Edge is a data ingestion and analytics tool for IoT and cybersecurity edge systems that runs via an ultralight agent.
  • Data Protector discovers and secures sensitive data as it moves through a pipeline, to aid compliance with GDPR, HIPAA, and other regulations.
  • DataFlow Performance Manager adds historical comparisons and data SLAs for availability, accuracy, and security.
StreamSets Data Collector (SDC) supports more than 40 storage and database sources, plus Kafka Streams and MapR Streams; no SaaS integrations are available other than Salesforce. Destinations include Google BigQuery, Snowflake, Amazon S3, Microsoft Azure SQL Data Lake, and more than 30 other database, storage, and streaming platforms.

AWS Glue

AWS Glue supports AWS data sources — Amazon Redshift, Amazon S3, Amazon RDS, and Amazon DynamoDB — and AWS destinations, as well as various databases via JDBC. Glue can also serve as an orchestration tool, so developers can write code that connects to other sources, processes the data, then writes it out to the data target.

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.

StreamSets

StreamSets provides support through a Zendesk ticketing system. Documentation is comprehensive. Digital training materials are available.

AWS Glue

AWS provides several levels of support. Free Basic support provides access to support forums. Develop support adds client-side diagnostic tools and guidance on how to use AWS products, features, and services together. Business and Enterprise plans add additional options. Documentation is comprehensive. Both digital training and classroom training services 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.

Pricing

StreamSets

StreamSets provides a 30-day free trial. Pricing isn't disclosed.

AWS Glue

AWS Glue ETL jobs are billed at an hourly rate based on data processing units (DPU), which map to performance of the serverless infrastructure on which Glue runs. For the AWS Glue Data Catalog, users pay a monthly fee for storing and accessing Data Catalog the metadata. The first million objects stored are free, and the first million accesses are free. A development endpoint provisioned to interactively develop ETL code is billed per second.

Stitch

Stitch has pricing that scales to fit a wide range of budgets and company sizes. All new users get an unlimited 14-day trial. After the trial, there's a free plan for smaller organizations and nonproduction workloads. Standard plans range from $100 to $1,250 per month depending on scale, with discounts for paying annually. Enterprise plans for larger organizations and mission-critical use cases can include custom features, data volumes, and service levels, and are priced individually.
