海外TECH	DEV Community	Data Migration from Monolith to Microservice in Django	https://dev.to/balwanishivam/data-migration-from-monolith-to-microservice-in-django-5b9m	Data Migration from Monolith to Microservice in Django IntroductionMonolith Architecture is a design model for a software program Under this design model we follow a traditional approach of a unified program i e whole code is composed in one single piece Due to a unified approach monolith architecture does not provide flexibility in terms of size and changes If the application is too large then changes or updates are difficult to make Continuous development is difficult due to a unified architecture and also fault detection is difficult Due to a unified architecture it provides a restriction both in size and complexity of maintenance To overcome the shortcomings of monolith architecture nowadays microservices are used The main idea of microservices is to break the unified architecture into smaller segments and interconnect them using such a design we would reduce complete failure of the system due to breaking at one point and also help in the maintenance testing and continuous integration To break a monolith into microservices we need to make microservices in such a way that it is interconnected to others but also be able to stand alone in times when an interconnected microservices breaks off or if one microservice face downtime or some bug then it should not lead to whole system failure In this article we would learn about how to separate the data of a microservice already present from a monolith and populate it into the database linked with the microservice using Django management commands We would learn about Django Management commands and how data migration can be done using these commands What is Django Django is a python high level web framework that helps in rapid and clean development It is free and open source Django provides features like fast secure and scalable thus making it one of the most popular choices for web development What are Django Management commands Django management commands are a part of Django apps that provide us the ability to fulfill repetitive or complex tasks through a one keyword command line instruction Every management command has a proper script that defines how the command has to be executed in order to perform tasks How to migrate data from monolith to microservice In order to perform the migration we need to follow the below steps to get and populate the data of a microservice present in a monolith to the microservice database A management command at monolith to filter out the data related to the microservice present in monolith in a specific format like JSON or CSV here I will be using JSON Use this JSON or CSV file and extract the data and populate them in Microservice Database Step Extracting data from monolithThis will be a management command in python so we need to write this under the following directory django app name management commands fetch data file name py Code import jsonimport sysfrom django core management base import BaseCommandfrom django core serializers json import DjangoJSONEncoderclass Command BaseCommand help Extracting user data to JSON format def handle self args options Get User Data from User Model in monolith user microservice data User objects all for user data in user microservice data data model User id user data id username user data flip collection id mobile number user data flip image id created at user data created at Dumping Data into JSON Format json dump data sys stdout cls DjangoJSONEncoder sys stdout write n After saving this command extract using the following shell command python manage py fetch data gt data file name json Step Populating the Microservice database using this JSON FileFor this we will again need to write a management command on microservice project and upload the json file in microservice project Directory django app name management commands populate data file name py Code import jsonimport sysimport loggingfrom dateutil import parserfrom django core management base import BaseCommandlogger logging getLogger name class Command BaseCommand help Populating User data obtained in JSON from Monolith def handle self args options for line in sys stdin data json loads line Populating User Model if data model User user User user id data id username data username mobile number data mobile number created at parser parse data created at user save logger debug User populated format user user id After saving this command populate using the following shell command cat data file name json gt python manage py populate data Conclusion The above process is a sample code about how you can extract data from monolith and populate in microservice The above code can be used to get a JSON containing data of multiple tables of monolith in a same file We can use other file types too like CSV etc Bulk create could also be used in Django to save all entries in one go	2021-09-04 18:37:11
