Used to stop a Push collection from performing caching on PUT or DELETE calls.
Can be set in: collection.cfg
Used to prevent push collection from returning until the changes made by PUT or DELETE calls are written to disk. A commit operation always causes pending changes to be written before committing, so this change simply ensures that changed which have been submitted but have not yet been committed will not be lost if power is suddenly lost.
By default, push may return before PUT and DELETE calls have written their changed to disk to improve the performance of API calls.
