gRPC 2 UNKNOWN vs 15 DATA_LOSS
Both gRPC 2 (UNKNOWN) and 15 (DATA_LOSS) belong to the gRPC Status Codes category. 2 indicates that an unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code. Meanwhile, 15 means that unrecoverable data loss or corruption has occurred.
Beschreibung
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
Wann Sie es sehen
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
Wie man es behebt
Check the server logs for the underlying exception. Wrap server-side errors with explicit gRPC status codes instead of letting them bubble up as UNKNOWN.
Beschreibung
Unrecoverable data loss or corruption has occurred.
Wann Sie es sehen
Critical data was lost or corrupted — for example, a checksum mismatch during transmission or an unrecoverable storage failure on the server.
Wie man es behebt
Investigate the data integrity failure immediately. Restore from backups if available, and check for hardware failures or network corruption in the data path.
Wesentliche Unterschiede
gRPC 2: An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
gRPC 15: Unrecoverable data loss or corruption has occurred.
You encounter 2 when the server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
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.
