# // **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;
# //     }

# // Example message:
# //
# //     {
# //       table_name: projects/proj_foo/instances/instance_bar/table/table_baz,
# //       app_profile_id: profiles/prof_qux

# // The routing header consists of one or multiple key-value pairs. The order of

# // the `RoutingRule` only matters for the evaluation order of the path
# // templates when `field` is the same. See the examples below for more details.
