gRPC 6 ALREADY_EXISTS vs 10 ABORTED
Both gRPC 6 (ALREADY_EXISTS) and 10 (ABORTED) belong to the gRPC Status Codes category. 6 indicates 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. Meanwhile, 10 means that the operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
描述
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.
何时出现
A create operation failed because a resource with the same unique identifier or name already exists in the system.
如何修复
Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating.
描述
The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
何时出现
A transaction or optimistic concurrency check failed — for example, a read-modify-write cycle detected a conflict with another concurrent operation.
如何修复
Retry the entire read-modify-write sequence from the beginning. Implement proper optimistic concurrency control with version tokens or ETags.
主要区别
gRPC 6: 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.
gRPC 10: The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
You encounter 6 when a create operation failed because a resource with the same unique identifier or name already exists in the system.
You encounter 10 when a transaction or optimistic concurrency check failed — for example, a read-modify-write cycle detected a conflict with another concurrent operation.
何时使用哪个
For 6 (ALREADY_EXISTS): Use a different identifier, or switch to an upsert/update operation if overwriting is acceptable. Check for existing resources before creating. For 10 (ABORTED): Retry the entire read-modify-write sequence from the beginning. Implement proper optimistic concurrency control with version tokens or ETags.
