<s>[INST] In MongoDB, how many collections are to many? I have 600 categories i want to track items in, do I create 600 collections or 1, where every item has the field "category"? [/INST] MongoDB does not have many hard limits on the amount of collections you can have, and it depends on what kind of project you are working on. For your usecase, it may be best to have one collection with a field called "category" as you considered.</s>\ <s>[INST] Can you tell me the pros and cons of making 600 collections versus making 1 where every item has the field "category"?   If you can, please provide data on performance using one methodology over the other.   I'd like to know how fast this is going to be. [/INST] a random question related to coding
