[GitHub] [arrow] sunpe opened a new issue, #35330: Ipc writer in concurrent will write schema twice

sunpe opened a new issue, #35330:
URL: https://github.com/apache/arrow/issues/35330

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   When using ipc writer under concurrent conditions, schema data may be written multiple times. And the data sink may crash with an error.
   
   Demo as below:
   ```
   schema := arrow.NewSchema(...)
   
   address, err := net.ResolveTCPAddr("tcp", '127.0.0.1')
   if err!=nil {
       ...
   }
   conn, err := net.DialTCP("tcp", nil, address)
   if err!=nil {
       ...
   }
   
   writer := ipc.NewWriter(conn, ipc.WithSchema(schema))
   
   record  :=  ... // create record
   for i:=0; i< 10; i++ {
       go func() {
           if err = writer.Write(record); err != nil {
                ...
           }
       }()
   }
   ```
