gRPC 1 CANCELLED vs 4 DEADLINE_EXCEEDED
Both gRPC 1 (CANCELLED) and 4 (DEADLINE_EXCEEDED) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 4 means that the deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully.
विवरण
The operation was cancelled, typically by the caller.
जब आप इसे देखें
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
कैसे ठीक करें
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
विवरण
The deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully.
जब आप इसे देखें
The RPC took longer than the configured deadline allows. Common in slow network conditions, overloaded servers, or when the deadline is set too aggressively.
कैसे ठीक करें
Increase the client deadline, optimize the server-side processing, or add server-side caching. If the operation might have succeeded, check idempotency before retrying.
