Extending nodes for in database processing

Can we override existing node (or new custom node) methods such as configure(), execute(), reset() to do data intensive processing activities such as manipulation, transformation, scoring etc in a database server (source) itself instead of executing them outside the database (in Knime)?

I am not sure, if this should be the recommended way to go. Actually that’s why we have made them all package visible only. I would suggest using the database auxiliary class from the core package “org.knime.core.node.port.database”, when you planning to implement your own database node. Best, Thomas
