+//
+// 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:
+//

+//       app_profile_id: profiles/prof_qux

+// In the examples below I am skipping the percent-encoding for readablity.
