In Juno, developers can create as many “collections” as they want, both in heap or stable memory, to save their data. Currently, if they opt for stable memory, there is one unique StableTreeMap that contains every entry, with the collection used as part of the key. However, this doesn’t feel very performant, which is why I want to create one tree map per collection dynamically. With the current limitation, it would mean that I would have to limit the number of collections to, for example, 100 or 150. Not sure one would require as many collection but, given that I would have to set a limit, I thought about asking first.
