> create a query for cloudkit which will perform an operation
Given what you mean by "operation", no, you must download the record (*) and do the calculation yourself.
* You can download only the fields you want with:
Thanks for your reply.
(Yes I was meaning a maths operation, not a query operation.)
How many returned records do you think is acceptable?
I am working on a project where the returned records could number in the 10s of thousands!
I probably need to return five fields per record. (mixture of strings and numbers)
I have never had to return this many results before from cloudkit and don't know if this is acceptable, or what type of delays I can expect?
It may not be that bad. You use a token and recursively call the query with the token.
