Good morning

Im new in Pytables and I have a simple question, please help me.

I have a pytable created with four Float() columns, the number of rows
in the table is around 500.000. I need to read all the complete table
in fastest way possible to a numpy array in memory.  Im using the
following command:

   total =[ (x['col1'],x['col2'],x['col3'],x['col4'],) for x in row_relational]

Question: Is there another command that allows to read in a fastest way?

Many thanks

German
