      • (dict) --

        Describes the state of a traffic source.

        • TrafficSource (string) --

        • State (string) --

          The following are the possible states for a VPC Lattice target group:

          • Adding - The Auto Scaling instances are being registered with the target group.
          • Added - All Auto Scaling instances are registered with the target group.
          • InService - At least one Auto Scaling instance passed the VPC_LATTICE health check.
          • Removing - The Auto Scaling instances are being deregistered from the target group. If connection draining is enabled, VPC Lattice waits for in-flight requests to complete before deregistering the instances.
          • Removed - All Auto Scaling instances are deregistered from the target group.
    • NextToken (string) --

      This string indicates that the response contains more items than can be returned in a single response. To receive additional items, specify this string for the NextToken value when requesting the next set of items. This value is null when there are no more items to return.
