I am using DrWatson, and many times I run Monte Carlo simulation which result in large data. As an example you can think of a time sequence, where each element in the sequence is a matrix.  
Sometimes, the simulation prepares many such time sequences, which results in large data.  
When I load the results using `collect_results`, I get that each row hold a lot of information.  
I can then handle the proper separation in code.

My main issue is that if I forget to add `;` at the end of a line which returns the DataFrame, the jupyter notebook get stuck as it need a lot of memory to present the information.  
This causes me to think that I am implementing my Monte Carlo data saving wrong. If anyone has good suggestions on how to save or load things properly it would be nice to hear!

(BTW, I am aware of this [question](https://discourse.julialang.org/t/examples-of-a-database-to-manage-simulation-result-files/55063), however I do not really want to use a database. I don’t think it necessary for my case).
