gRPC 1 CANCELLED vs 14 UNAVAILABLE
Both gRPC 1 (CANCELLED) and 14 (UNAVAILABLE) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 14 means that the service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff.
설명
The operation was cancelled, typically by the caller.
이 코드를 보게 되는 경우
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
해결 방법
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
설명
The service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff.
이 코드를 보게 되는 경우
The server is overloaded, shutting down, or a network partition occurred. This is the most common code to retry on, as it's explicitly transient.
해결 방법
Retry with exponential backoff. If persistent, check the server health, load balancer configuration, and network connectivity between client and server.
