It’s just references to the database nodes. To learn more about the memory consumption of particular operations, you can attach a profile function call to map:merge and check out the output in the info view panel of the GUI (or see what the command line returns): let $originalDB.map := map:merge( for $entry in $originalDB return map:entry($entry/@id, $entry) ) => prof:memory()
