    Description

      The used named_tuple class from collections module is

      • too slow
      • consumes too much memory

      How to repeat:

      import mariadb
      		 
       
      		 
      connection= mariadb.connect(db="test")
      		 
      cursor= connection.cursor(named_tuple=True)
      		 
      for in range(1,1000):
      		 
          cursor.execute("SELECT seq FROM seq_1_to_10000")
      		 
          rows= cursor.fetchall()

      Output:

      georg@beethoven:~/work/python/test$ python3.10 test_conpy227.py
      		 
      Killed

      Same behavior when running this script with MySQL Connector/Python, which also uses collections.named_tuple.
