How memory is consumed when column rename node is used after lag column?

Hi Everyone,

I’m new to KNIME, I would like to know how the memory consumption is done in KNIME when using sorter → lag Node → rule engine → column Renamer → row filter → column filter

Here, the 4 nodes (sorter, lag Node, rule engine, column Renamer) and other 2 ( row filter, column filter) are having same number of rows as output respectively. Does it mean 4 nodes are consuming the 4 times of memory?
