   > Thanks! I'll take a look later. Just a quick sanity check, can you test if you could do `spark.write` in the listener and in the client verify if the write is there? For example:
   > 
   > ```
   > >>> class MyListener(ConnectStreamingQueryListener):
   > ...     def onQueryStarted(self, event: QueryStartedEvent) -> None: 
   >              print("hi, event query id is: " +  str(event.id)); 
   >              df=spark.createDataFrame(["10","11","13"], "string").toDF("age"); 
   >             df.write.saveAsTable("tbllistener")
   > ```
   > 
   > and do a `spark.read.table()` in client repl
   
   Sure, will do that, thanks!
