Root Cause

The server detected a concurrent modification conflict, often due to optimistic locking or transaction conflicts.

generic

中文

服务器检测到并发修改冲突，通常由于乐观锁或事务冲突。

Workarounds

  1. 90% success 
    for i := 0; i < 5; i++ {
    resp, err := client.YourMethod(ctx, req)
    if err == nil { break }
    if status.Code(err) == codes.Aborted {
        time.Sleep(time.Duration(1<<i) * time.Second)
        continue
    }
    return err
}
  2. 85% success 
    // Include a version field in your request and have the server check it.
// On conflict, fetch the latest version and retry.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Immediate retries can exacerbate contention and lead to more conflicts.

  2. 95% fail

    Disabling concurrency control can lead to data corruption and is not acceptable.
