   - Corresponding `watch_id` is returned via `etcdserverpb.WatchResponse`, if any.
+- Add [`fragment` field to `etcdserverpb.WatchCreateRequest`](https://github.com/coreos/etcd/pull/9291) to request etcd server to [split watch events](https://github.com/coreos/etcd/issues/9294) when the total size of events exceeds `--max-request-bytes` flag value plus gRPC-overhead 512 bytes.
+  - The default server-side request bytes limit is `embed.DefaultMaxRequestBytes` which is 1.5 MiB plus gRPC-overhead 512 bytes.
+  - If watch response events exceed this server-side request limit and watch request is created with `fragment` field `true`, the server will split watch events into a set of chunks, each of which is a subset of watch events below server-side request limit.
+  - For example, watch response contains 10 events, where each event is 1 MiB. And server `--max-request-bytes` flag value is 1 MiB. Then, server will send 10 separate fragmented events to the client.
+  - For example, watch response contains 5 events, where each event is 2 MiB. And server `--max-request-bytes` flag value is 1 MiB and `clientv3.Config.MaxCallRecvMsgSize` is 1 MiB. Then, server will try to send 5 separate fragmented events to the client, and the client will error with `"code = ResourceExhausted desc = grpc: received message larger than max (...)"`.

 - Add [`raftAppliedIndex` field to `etcdserverpb.StatusResponse`](https://github.com/coreos/etcd/pull/9176) for current Raft applied index.
 - Add [`errors` field to `etcdserverpb.StatusResponse`](https://github.com/coreos/etcd/pull/9206) for server-side error.
