Hi, I would like to know about the limitation of MongoDB atlas limitation. Assume I have 30k user in my app and they are continuously doing crud operation. Each user has limited data. Can mongoDB atlas free tier can handle that? The 512mb storage will not exceed but is there any limitation of writing or reading from database? If free tier has limitation for reading and writhing for limited amount then what option will be better for my 30k user? Please let me know the details.
