// Starts a new task using the specified task definition.

// before authorization. When a task definition revision is not specified,
// authorization will occur using the latest revision of a task definition.

// You can allow Amazon ECS to place tasks for you, or you can customize how
// Amazon ECS places tasks using placement constraints and placement strategies.
// For more information, see [Scheduling Tasks]in the Amazon Elastic Container Service Developer
// Guide.
//
// Alternatively, you can use StartTask to use your own scheduler or place tasks
// manually on specific container instances.
//
// You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume
// when creating or updating a service. For more infomation, see [Amazon EBS volumes]in the Amazon
// Elastic Container Service Developer Guide.
//
// The Amazon ECS API follows an eventual consistency model. This is because of
// the distributed nature of the system supporting the API. This means that the
// result of an API command you run that affects your Amazon ECS resources might
// not be immediately visible to all subsequent commands you run. Keep this in mind
// when you carry out an API command that immediately follows a previous API
// command.
//
// To manage eventual consistency, you can do the following:
//
//   - Confirm the state of the resource before you run a command to modify it.
//   Run the DescribeTasks command using an exponential backoff algorithm to ensure
//   that you allow enough time for the previous command to propagate through the
//   system. To do this, run the DescribeTasks command repeatedly, starting with a
//   couple of seconds of wait time and increasing gradually up to five minutes of
//   wait time.
//
//   - Add wait time between subsequent commands, even if the DescribeTasks
//   command returns an accurate response. Apply an exponential backoff algorithm
//   starting with a couple of seconds of wait time, and increase gradually up to
//   about five minutes of wait time.
