If you are a back-end developer, you are often faced with having to migrate your database schema with each new release.
The framework called Liquibase can make it easier for you when you need to upgrade your database schema.
In this article, I’ll explain how Liquibase can be used in a Java project, with Spring/Hibernate, to version the database schema.
Changelog
Liquibase works with Changelog files (the list of all the changes, in order, that need to execute to update the database).
There are 4 supported formats for these Changelogs: SQL, XML, YAML, and JSON.
#liquibase #database #versioning #plugins #java #hackernoon-top-story #database-schema-versioning #database-schema-migration

A simple Boilerplate to Setup Authentication using Django-allauth, with a custom template for login and registration using django-crispy-forms
.
# clone the repo
$ git clone https://github.com/yezz123/Django-Authentication
# move to the project folder
$ cd Django-Authentication
virtual environment
for this project:# creating pipenv environment for python 3
$ virtualenv venv
# activating the pipenv environment
$ cd venv/bin #windows environment you activate from Scripts folder
# if you have multiple python 3 versions installed then
$ source ./activate
SECRET_KEY = #random string
DEBUG = #True or False
ALLOWED_HOSTS = #localhost
DATABASE_NAME = #database name (You can just use the default if you want to use SQLite)
DATABASE_USER = #database user for postgres
DATABASE_PASSWORD = #database password for postgres
DATABASE_HOST = #database host for postgres
DATABASE_PORT = #database port for postgres
ACCOUNT_EMAIL_VERIFICATION = #mandatory or optional
EMAIL_BACKEND = #email backend
EMAIL_HOST = #email host
EMAIL_HOST_PASSWORD = #email host password
EMAIL_USE_TLS = # if your email use tls
EMAIL_PORT = #email port
change all the environment variables in the
.env.sample
and don't forget to rename it to.env
.
After Setup the environment, you can run the project using the Makefile
provided in the project folder.

The moving of applications, databases and other business elements from the local server to the cloud server called cloud migration. This article will deal with migration techniques, requirement and the benefits of cloud migration.
In simple terms, moving from local to the public cloud server is called cloud migration. Gartner says 17.5% revenue growth as promised in cloud migration and also has a forecast for 2022 as shown in the following image.

At first, we didn’t consider an auto-migrating solution because there wasn’t a lot of complexity in the migration, especially for our small databases. We’d just have to bring the application down, export the database, import it to Cloud SQL, and bring it back up. That worked for most of our applications.
But toward the end of the process, two applications remained.
Through conversations with our product team and our Google contact, we learned about the Google Cloud’s Database Migration Service (which was in private preview at the time), which provides a serverless migration experience from MySQL to Cloud SQL for MySQL with continuous data replication, at no additional cost.
