+// ProfilerService provides API for recording the profiling data from profiling
+// agents running as part of a GCP deployment being profiled or from an offline
+// provider of profiling data.
+//
+// General guidelines:
+// * Profiles for a single deployment must be created in ascending time order.
+// * Profiles can be created in either online or offline mode, see below.
+service ProfilerService {
+  // CreateProfile creates a new profile resource.
+  //
+  // In the online creation mode:
+  // * The server ensures that the new profiles are created at a constant rate
+  //   per deployment, so the creation request may hang for some time until the
+  //   next profile session is available.
+  // * The request may fail with ABORTED error if the creation is not
+  //   available within ~1m, the response will indicate the duration of the
+  //   backoff the client should take before attempting creating a profile
+  //   again. The backoff duration is returned in google.rpc.RetryInfo extension
+  //   on the response status. To a gRPC client, the extension will be return as
+  //   a binary-serialized proto in the trailing metadata item named
+  //   "google.rpc.retryinfo-bin".
+  //
+  // In the offline creation mode:
+  // * The client provides the profile to create along with the profile bytes,
+  //   the server records it.
+  rpc CreateProfile(CreateProfileRequest) returns (Profile);
