Node Development

Hello community developers,

KNIME Analytics Platform 5.4.0 comes with lots of enhancements and improvements. Below are some top highlights.

  • K-AI: Pre-installed with enhanced workflow building and integrated Hub support for faster, smarter assistance.
  • AI Extension: Improved LLM prompter for simplified prompting and faster responses, new nodes to connect with chat and embeddings models in Databricks workspaces, Giskard nodes for GenAI evaluation, and a new node to update and migrate vector stores that simplify the maintenance of knowledge bases in GenAI workflows. Added GPT4All support for IBM Granite and Microsoft Phi 3.5, giving users more local model options without privacy or cloud cost concerns.
  • Expressions Nodes: The Expressions node now supports multiple expressions, enabling users to reuse results from earlier expressions. A new Expression Row Filter node offers advanced filtering and the new Variable Expression node supports variable handling, simplifying complex data manipulations. All Expressions nodes come with the same expression language and AI assistance.
  • Database Updates: A new Databricks SQL Connector node, improved Snowflake Connector node with OpenSSL V3, and auto-updating drivers for connectors like Athena and BigQuery.
  • Node Enhancements: New Tableau Reader node and a more secure version of SSH Command Executor node.
  • View Improvements: Easy filtering of legend items in views with a double click and improved SVG-supported reporting.
  • Table View Enhancements: New cell detail view to enlarge the cell content while still keeping the table compact.
  • Embedded Dialogs: Experimental side-panel dialogs for smoother navigation that can be enabled in Preferences.
  • Node Repository Tree View: New categorized view for easier node discovery.
  • Product Hints for New Users: Onboarding tips to help new users explore KNIME concepts and tools.

Updates and Compatibility

  • Node API: Plug-in org.knime.core and org.knime.core.util no longer re-export the java package org.apache.commons.io*, 3rd party extensions might need to declare an explicit plug-in dependency in their MANIFEST.MF
  • Node API: The (deprecated) method NodeFactory#addLoadedFactories has been filled in empty. 3rd party must register nodes via extension points. (Method was deprecated since version 4.2.)
  • Authentication popups provided by the Eclipse platform are suppressed globally. If an extension needs the popup to provide username and password authentication, set the Java system property knime.auth.popups.allowed to true.
  • Perspective in Modern UI: All nodes are shown in the node repository (vs “Starter Nodes” only, as previously done in 5.3.x and before). This can be changed via preference setting.
