-- | Creates a value of 'CreateTrigger' with the minimum fields required to make a request.

-- Use one of the following lenses to modify other fields as desired:
--
-- * 'ctSchedule' - A @cron@ expression used to specify the schedule (see <http://docs.aws.amazon.com/glue/latest/dg/monitor-data-warehouse-schedule.html Time-Based Schedules for Jobs and Crawlers> . For example, to run something every day at 12:15 UTC, you would specify: @cron(15 12 * * ? *)@ . This field is required when the trigger type is SCHEDULED.
--
-- * 'ctPredicate' - A predicate to specify when the new trigger should fire. This field is required when the trigger type is CONDITIONAL.
--
-- * 'ctStartOnCreation' - Set to true to start SCHEDULED and CONDITIONAL triggers when created. True not supported for ON_DEMAND triggers.
--
-- * 'ctDescription' - A description of the new trigger.
--
-- * 'ctName' - The name of the trigger.
--
-- * 'ctType' - The type of the new trigger.
--
-- * 'ctActions' - The actions initiated by this trigger when it fires.
