Well this morning using CloudKit is a very different experience. Clearly the API block has expired and I was able to clean the CloudKit sync store and upload again from scratch using the latest DTTG without any issues.
I was on the naughty step for 2 days this time!
It also seems considerably faster, although I can’t tell if that’s the new DTTG or because previously there had been a throttling issue with the Apple service.
It occurred to me that I always have “verify uploaded items” turned on, which must double the traffic. I wonder if this might be more likely to trigger throttling since (presumably) it hits the service twice as hard?
Interesting point. If the documents were uploaded to a proprietary service then the service could generate a checksum that could be compared with one generated client side.
Some of the sync stores are essentially dumb file buckets (like WebDAV) where the only way I can think that verification could work is to re-download and compare the fetched file.
But maybe Dropbox or iCloud have a feature like this. it does make sense for a file store designed for syncing and versioning.
Ok, yes thanks. I was only trying to give Jim some feedback on his earlier question regarding whether “verify uploaded items” was on when I was experiencing problems. I don’t have a problem of any sort now.
For info… I re-tested Cloudkit sync with the latest versions of DT and DTTG with no issue so I have switched my entire set of databases over - not one problem and sync is working fine and very fast too.
I’m still slightly suspicious that the chronic throttling issue was some apple service problem that they quietly resolved. At first it was working, then I was having trouble for days and suddenly it was fine again. And all with no action on my part and seemingly unrelated to the most recent DTTG update, since the problem persisted for a while after I updated. Still - all good now!
Reminds me of this, when Steve Jobs fired the head of the iCloud team
I‘m wondering if this problem is still „unsolved“ as I got so consistent CloudKit sync errors due to the rate limit that I had to completely shut-off the cloud sync and switch to my own WebDAV solely.
Other observation is that my 10 GB DB used 31 GB in icloud.
