/// Specifies the routing information that should be sent along with the request

/// **NOTE:** All service configuration rules follow the "last one wins" order.
///
/// The examples below will apply to an RPC which has the following request type:
///
/// Message Definition:
///
///     message Request {
///       // The name of the Table
///       // Values can be of the following formats:
///       // - `projects/<project>/tables/<table>`
///       // - `projects/<project>/instances/<instance>/tables/<table>`
///       // - `region/<region>/zones/<zone>/tables/<table>`
///       string table_name = 1;
///
///       // This value specifies routing for replication.
///       // It can be in the following formats:
///       // - `profiles/<profile_id>`
///       // - a legacy `profile_id` that can be any string
///       string app_profile_id = 2;
///     }
