thread in odoo

Let us say we have 10000 employees record and we want to increase the performance of processes on these records , in this case we can use the thread 

So :

 

Tread is away to distribute the work into many processes which are running at the same time , and that will increase the performance of our server

Example :- 

   let us say that we want to display the multiplication table of number inserted by the user 

   we will define the object which contain the fields and the functions , then create four function each one make the multiplication table for the number with only 3 numbers , then we will call the four functions at the same time by using threads

from odoo import models, fields, api, _ 

import threading

class multiplication_table(models.Model):
    _name = 'multiplication.table'

    

    number = fields.Interger('Number', required=True)

    def thread1(self):

          for x in xrange(1,4):

                print (self.number," * ",x,"=",self.number*x)

   
    def thread2(self):

          for x in xrange(4,7):

                print (self.number," * ",x,"=",self.number*x)

    def thread3(self):

          for x in xrange(7,10):

                print (self.number," * ",x,"=",self.number*x)

    def thread4(self):

          for x in xrange(10,13):

                print (self.number," * ",x,"=",self.number*x)

    t1= threading.Thread(target=self.thread1, args=())

    t2= threading.Thread(target=self.thread2, args=())

    t3= threading.Thread(target=self.thread3, args=())

    t4= threading.Thread(target=self.thread4, args=())

    t1.start()

    t2.start()

    t3.start()

    t4.start()
