gRPC 4 DEADLINE_EXCEEDED vs 15 DATA_LOSS
Both gRPC 4 (DEADLINE_EXCEEDED) and 15 (DATA_LOSS) belong to the gRPC Status Codes category. 4 indicates 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. Meanwhile, 15 means that unrecoverable data loss or corruption has occurred.
الوصف
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.
متى تراه
The RPC took longer than the configured deadline allows. Common in slow network conditions, overloaded servers, or when the deadline is set too aggressively.
كيفية الإصلاح
Increase the client deadline, optimize the server-side processing, or add server-side caching. If the operation might have succeeded, check idempotency before retrying.
الوصف
Unrecoverable data loss or corruption has occurred.
متى تراه
Critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
كيفية الإصلاح
Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
