Lazy loading

[InfiniteRegression]

I am saving large data to variables and would, rather than having them all load in memory, have them only load when required. Basically I am serializing the entire data set but at any instance will use only one record from it. While I still need to load all the records, I do not want to load the large data with it. just partly. When it is used, I can load the data. While I could do this manually, it would be nicer if orange directly supported some type of lazy loading attribute.

I'm not sure I understand. Could you please provide a minimal example?
