gRPC 8 RESOURCE_EXHAUSTED vs 16 UNAUTHENTICATED
Both gRPC 8 (RESOURCE_EXHAUSTED) and 16 (UNAUTHENTICATED) belong to the gRPC Status Codes category. 8 indicates that some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space. Meanwhile, 16 means that the request does not have valid authentication credentials for the operation.
説明
Some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.
このコードが表示される場合
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.
解決方法
Implement exponential backoff and retry. If quota-related, request a quota increase or optimize your usage pattern to stay within limits.
説明
The request does not have valid authentication credentials for the operation.
