• To workaround the 'grpc: received message larger than max' error in RisingWave, you can set the --max-request-bytes parameter for the etcd pod.

• This parameter can help in handling large requests to etcd and prevent the error from occurring.

• Here is an example of how you can set the --max-request-bytes parameter for the etcd pod:

kubectl edit pod <etcd-pod-name> -n <namespace>

• Add the following line under the spec section of the pod configuration:

containers:
  - name: etcd
    command:
      - /usr/local/bin/etcd
      - --max-request-bytes=<max-bytes>

• Replace <etcd-pod-name> with the name of the etcd pod and <namespace> with the namespace where the pod is deployed.
• Set <max-bytes> to the desired maximum request size in bytes.
