Lifecycle of nodes in the KNIME server


Say in my workflow, I have a database connector node that i configure to produce a database connection.

Can i reuse the same database connection across multiple workflow invocations (via the web service)?

I do not want to open a new database connection everytime the workflow is invoked.



Hi Kenny,

the database connections are cached in KNIME based on the database url and the user name. So if all your workflows run in the same KNIME instance and connect to the same database with the same user credentials they all use one connection.
