gRPC 4 DEADLINE_EXCEEDED vs 6 ALREADY_EXISTS
Both gRPC 4 (DEADLINE_EXCEEDED) and 6 (ALREADY_EXISTS) 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, 6 means that the entity that a client attempted to create already exists. For example, a file or directory that the RPC was supposed to create already exists.
Deskripsi
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.
Ketika Anda Melihatnya
The RPC took longer than the configured deadline allows. Common in slow network conditions, overloaded servers, or when the deadline is set too aggressively.
Cara Memperbaiki
Increase the client deadline, optimize the server-side processing, or add server-side caching. If the operation might have succeeded, check idempotency before retrying.

A create operation failed because a resource with the same unique identifier or name already exists in the system.
Cara Memperbaiki
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.
