Root Cause

The operation was aborted due to a concurrency conflict, such as an optimistic locking failure where the resource version changed.

generic

中文

由于并发冲突（例如乐观锁失败导致资源版本更改），操作被中止。

Workarounds

  1. 95% success 
    for {
    resource, err := client.Get(ctx, &GetRequest{Id: id})
    if err != nil { return err }
    resource.Data = newData
    _, err = client.Update(ctx, resource)
    if status.Code(err) != codes.Aborted {
        return err
    }
    // retry
}
  2. 90% success 
    // Include version in the update request
req := &UpdateRequest{Id: id, Data: newData, Version: currentVersion}
_, err := client.Update(ctx, req)
if status.Code(err) == codes.Aborted {
    // handle conflict
}

Dead Ends

Common approaches that don't work:

  1. 100% fail

    The version is outdated; retrying with the same version will fail again.

  2. 90% fail

    This can lead to lost updates and data inconsistency.
