A quick question on this... (First of all thanks so much for the sample code!). I'm playing around with this and I would like to get the statement_type and status. I see that duration, query_start_time_ms and query_end_time_ms are int data type and defines as LongType(); executed_as_user_name and query_text are str datatype and defined as StringType. statement_type and status are listed as data types QueryStatementType and QueryStatus respectively. How would I define the StructType for these fields?
