Address book and calendar sync tokens have a created_at column in 26+ and we need to assign a current timestamp to the existing data at upgrade so the data isn't cleaned up immediately. Updating the full table is expensive and fails on clustered setups that limit transaction size. We don't need a timestamp for the oldest rows so we can skip updating them.

| // The threshold is higher than the default of \OCA\DAV\BackgroundJob\PruneOutdatedSyncTokensJob | ||
| // but small enough to fit into a cluster transaction size. | ||
| // For a 50k users instance that would still keep 10 changes on average. | ||
| $limit = max(1, (int) $this->appConfig->getAppValue('totalNumberOfSyncTokensToKeep', '500000')); |
