KNIME_H2_Database as a transient temporary results store

Using an in-memory H2 database as a transient memory store for intermediate workflow results. This doesn't require writing to file store and the data disappears when the workflow is reset 20 April 2021, @takbb Brian Bates

I really like this approach - thanks so much for sharing - and it would definitely prevent workflows looking like spaghetti with extremely long connectors all over the place!

I’ve a couple of questions if ok…

  • I’m unfamiliar with H2 databases, are there any situations you wouldn’t use this approach? (ie. Table size too big, etc)
  • What’s the purpose of the ‘Container Output (Table)’ node within this workflow?

Thanks in advance!
