We’re using the PHP schedulerConnector class to link the schedule with our database, but have VERY full schedules with a lot of extra data associated with each appointment. The overhead from XML markup is causing slowdowns, so we’re looking to use JSON instead. Is there a version of this class that outputs the data in JSON format, or are we going to need to roll our own?
Unfortunately you can not configure schedulerConnector to output JSON.
As an option you may try using Dynamic loading (output will still be xml but with less data as events will be loaded per selected timeframe).
