I’m getting and error when attempting to refresh a few data sets “Query exhausted resources at this scale factor.” At first I thought it was because I have a number of data sets set to refresh at the same time but when triggering a refresh manually when no other Athena function is running I get the same error. It should be noted that the error is intermittent so it doesn’t happen every time I refresh the data set. Over the past week it successfully refreshed 4 times and failed 3 without any changes between refreshes.
Since this seems to be intermittent and to better help you I would suggest to open a ticket with our support team. They have access to the logs where we can find more information about the possible root cause.
