startFromHead

If the value is true, the earliest log events are returned first. If the value is false, the latest log events are returned first. The default value is true.

The startFromHead parameter sets the sort direction on the first request. On subsequent requests, the nextToken determines the sort direction. To continue paginating in the same direction, provide the returned nextToken. If you provide both nextToken and startFromHead, the direction of the nextToken is used.

Setting startFromHead to false is supported only when startTime is on or after Jan 1, 2024 00:00:00 UTC. A request with startFromHead set to false and a startTime before this date returns an InvalidParameterException.
