Streaming - Text Processing
This workflow demonstrates streaming in KNIME. Streaming is only possible for a selection of nodes. To enable streaming, you simply need to combine all streamable nodes in a component. In that way, downstream nodes can already execute with chunks of data, while upstream nodes are still executing. In the configuration dialog of the component under the "Job Manager Selection" tab, you can enable "simple streaming" and define the chunk size.
To find out which nodes are streamable, you can go to your Node Repository and click on the three dots next to the search. There you can either select "Show Streamable Nodes Only" to only see the streamable node or "Show Additional Info" to see the additional infos for each node.
