Creates or updates a rule. Rules are enabled by default, or based on value of the State parameter. You can disable a rule using DisableRule.
Note: When you create or update a rule, incoming events might not immediately
start matching to new or updated rules. Please allow a short period of time for changes to take effect.
A rule must contain at least an EventPattern or ScheduleExpression. Rules with EventPatterns are triggered when a matching event is observed. Rules with ScheduleExpressions self-trigger based on the given schedule. A rule can have both an EventPattern and a ScheduleExpression, in which case the rule will trigger on matching events as well as on a schedule.
Note: Most services in AWS treat : or / as the same character in Amazon
Resource Names (ARNs). However, CloudWatch Events uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event you want to match.
