WARN: Column Data Cache is disabled


I updated to the latest Knime 4.5. I am seeing the following Warnings in the workflows:

Column Data Cache is disabled. Consider enabling it in the Columnar Table Backend preferences

What is Column Data Cache used for?



It is a way to manage how and what memory is used for data in the workflow. It was developed starting in AP 4.3. For more information on Column Data Cache, please see [1].
