Due to the underlying nature of the AWS services used, especially the limits on IAM policy size, there are some restrictions on how many datasets a given user can be a member of at the same time. Basically AWS limits us to 20 6 Kb policies. If you need access to many datasets, remember to race the soft limit of 10 policies to 20. Since what would ideally be one large policy, have to split out over 20, in an automated way, there will necessarily be some waste of space. Also the length of dataset names will impact the total amount of datasets, but it should be safe to say that at around 5-600 datasets per user should be realistic, depending on the number of data zones chosen. There are no known limits on the number of datasets that can be created, or the number of nodes in the mesh.
