AWS::CloudTrail::Trail EventSelector
Use event selectors to further specify the management and data event settings for your trail. By default, trails created without specific event selectors will be configured to log all read and write management events, and no data events. When an event occurs in your account, CloudTrail evaluates the event selector for all trails. For each trail, if the event matches any event selector, the trail processes and logs the event. If the event doesn't match any event selector, the trail doesn't log the event.
You can configure up to five event selectors for a trail.
You cannot apply both event selectors and advanced event selectors to a trail.

CloudTrail supports data event logging for Amazon S3 objects in standard S3 buckets, Amazon Lambda functions, and Amazon DynamoDB tables with basic event selectors. You can specify up to 250 resources for an individual event selector, but the total number of data resources cannot exceed 250 across all event selectors in a trail. This limit does not apply if you configure resource logging for all data events.
For more information, see Data Events and Limits in Amazon CloudTrail in the Amazon CloudTrail User Guide.
