gRPC 1 CANCELLED vs 15 DATA_LOSS
Both gRPC 1 (CANCELLED) and 15 (DATA_LOSS) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 15 means that unrecoverable data loss or corruption has occurred.
Description
The operation was cancelled, typically by the caller.
When You See It
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
How to Fix
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
Description
Unrecoverable data loss or corruption has occurred.
When You See It
Critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
How to Fix
Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
Key Differences
gRPC 1: The operation was cancelled, typically by the caller.
gRPC 15: Unrecoverable data loss or corruption has occurred.
You encounter 1 when the client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
You encounter 15 when critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
When to Use Which
For 1 (CANCELLED): If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain. For 15 (DATA_LOSS): Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
