Seeking a means to have a persistent cloud based storage for structured data, I stumbled upon CloudExpressions, but, trying to update in place a cloud expression holding an association using iterated AssociateTo calls, I found it rather appalingly slow... But it may very well be the case that, due to my inexperience, I may not have used the most efficient update pattern...
Anyway, though having some wolfram language transparent cloud based structured storage and retrieval service is a very appealing option compared to having recourse to some other external web API, would you consider using cloud expressions as a viable option to persist the structured data of a Wolfram Cloud backed web application ?
Thanks for your comments.
