Is storing JSON objects in slots a good idea

I am wondering what should be typically stored in slots. In one of my bots, I plan to store JSON structures in slots to have access to objects (e.g. Events) and their related attributes. The structures can be quite large and it makes the slot carry lots of information that is probably not used in all sessions. Is this a problem for Rasa? What is a good practice in this matter?

What kind of info are you storing in these slots? Does the information come from an API?

Hi, yes the information comes from an API and describes business objects, in this case, machine failures. Those failures have an ID and some context data. One machine can have many failures at the same time. I only store the IDs in a list slot now but as the bot becomes more complex, I thought storing the entire object information is more efficient.
