PyODBC takes 6 seconds to establish a connection with Azure SQL Server

Question

PyODBC takes 6 seconds to establish a connection with Azure SQL Server, is there a way to minimize this?

import os
import sys
import logging, logging.handlers
import getopt
import pyodbc
from database import *

try:
conn = connect()
purgeStoreData(conn, DIV_ID, PURGE_DAYS, LOOKBACK_DAYS, STORE_START, STORE_END)
logger.info("*** Completed succesfully")
finally:
conn.close()

Answer 1

Could you please try to connect using the ODBC Driver 17 for SQL Server? You may find this way faster.

import pyodbc
server = '<server>.database.windows.net'
database = '<database>'
username = '<username>'
password = '{<password>}'   
driver= '{ODBC Driver 17 for SQL Server}'

with pyodbc.connect('DRIVER='+driver+';SERVER=tcp:'+server+';PORT=1433;DATABASE='+database+';UID='+username+';PWD='+ password) as conn:
    with conn.cursor() as cursor:
        cursor.execute("SELECT TOP 3 name, collation_name FROM sys.databases")
        row = cursor.fetchone()
        while row:
            print (str(row[0]) + " " + str(row[1]))
            row = cursor.fetchone()
