Both gRPC 0 (OK) and 8 (RESOURCE_EXHAUSTED) belong to the gRPC Status Codes category. 0 indicates that the operation completed successfully. Not an error; returned on success. Meanwhile, 8 means that some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.
Description
The operation completed successfully. Not an error; returned on success.
When You See It
The RPC completed without any issues. This is the expected response for every successful gRPC call.
How to Fix
No fix needed — this indicates everything worked correctly.
Description
Some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.
When You See It
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.
How to Fix
Implement exponential backoff and retry. If quota-related, request a quota increase or optimize your usage pattern to stay within limits.
Key Differences
gRPC 0: The operation completed successfully. Not an error; returned on success.
gRPC 8: Some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.

When to Use Which
For 0 (OK): No fix needed — this indicates everything worked correctly. For 8 (RESOURCE_EXHAUSTED): Implement exponential backoff and retry. If quota-related, request a quota increase or optimize your usage pattern to stay within limits.
