Batch Execution of KNIME Workflows, Part 2

In an earlier blog posting I walked through the steps required to install KNIME in a Docker container so that it could be used to run workflows in a batch mode.  This is a very useful technique for automating workflow execution and leveraging cloud resources to do so.  However, most workflows are not self-contained: they need access to configuration, external data, and local storage.   I did not cover those aspects in my first posting so this blog entry will introduce ways to pass in configuration and support the batch execution of KNIME workflows in a container. Setting Flow Variables The […]

Batch Execution of KNIME Workflows Using Docker

In my previous blog posting I introduced our service management platform Dex which is at the core of many of our advanced analytics solutions.  Dex seamlessly manages the coordination of the data acquisition, ingestion, transformation and modeling for our system via processing steps that are often deployed as Docker containers for execution on either dedicated servers, EC2 instances, or as AWS Fargate tasks.  One of the core applications we leverage for many of these steps is the open source KNIME analytics platform (www.knime.org).   KNIME’s easy to use GUI allows us to quickly develop and test ETL and modeling workflows.  Once […]
