Elastic Logstash vs. Pentaho Data Integration (Kettle) vs. Stitch
ETL software comparison
ETL software comparison
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.
Elastic is the corporate name of the company behind Elasticsearch. Logstash is a command-line tool that runs under Linux or macOS or in a Docker container. It integrates log data into the Elasticsearch search and analytics service. Elasticsearch, Logstash, and Kibana make up the company's ELK Stack.
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.
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.
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.
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.
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.

Each of these tools supports a variety of data sources and destinations.
Logstash 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.
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.
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.
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.
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.
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.
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.
Logstash is a free download, and is available bundled with other products in the Elastic Stack as a subscription, which starts at $16 per month. More expensive plans are available that feature things like dedicated support, custom plugins, machine learning, and advanced security features.
