gRPC 2 UNKNOWN vs 8 RESOURCE_EXHAUSTED
Both gRPC 2 (UNKNOWN) and 8 (RESOURCE_EXHAUSTED) 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, 8 means that some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.
Описание
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
Когда вы это видите
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
Как исправить
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.
Описание
Some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.
Когда вы это видите
A rate limit was hit, a quota was exceeded, or the server ran out of memory/disk. Common with API rate limiting and resource quotas.
Как исправить
Implement exponential backoff and retry. If quota-related, request a quota increase or optimize your usage pattern to stay within limits.
