I want to sync all my contacts (~900 contacts) from address book to cloudkit. I have a separate connection for synchronization between address book and my database where enumeration of contacts is performed. All saved contacts will be passed in YapDatabaseCloudKitRecordBlock when readWriteTransaction will be finished. YapDatabaseCloudKit sends all saved contacts to CloudKit. But operation fails with "Invalid Arguments" (12/1020); "Your request contains more than the maximum number of items in a single request (400)" error.

How i can limit a number of items in single request?
I didn't found setting for that.
