// DeregisterTaskDefinitionRequest returns a request value for making API operation for

//
// Deregisters the specified task definition by family and revision. Upon deregistration,
// the task definition is marked as INACTIVE. Existing tasks and services that
// reference an INACTIVE task definition continue to run without disruption.
// Existing services that reference an INACTIVE task definition can still scale
// up or down by modifying the service's desired count.
//
// You cannot use an INACTIVE task definition to run new tasks or create new
// services, and you cannot update an existing service to reference an INACTIVE
// task definition. However, there may be up to a 10-minute window following
// deregistration where these restrictions have not yet taken effect.
//
// At this time, INACTIVE task definitions remain discoverable in your account
// indefinitely. However, this behavior is subject to change in the future,
// so you should not rely on INACTIVE task definitions persisting beyond the
// lifecycle of any associated tasks and services.
