Continuous delivery is an extension of continuous integration to make sure that you can release new changes to your customers quickly in a sustainable way. This means that on top of having automated your testing, you also have automated your release process and you can deploy your application at any point of time by clicking on a button

Getting software released to users is often a painful, risky, and time-consuming process.

Continuous Delivery can help large organizations become as lean, agile and innovative as startups. Through reliable, low-risk releases, Continuous Delivery makes it possible to continuously adapt software in line with user feedback, shifts in the market and changes to business strategy. Test, support, development and operations work together as one delivery team to automate and streamline the build-test-release process.

Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.

By integrating regularly, you can detect errors quickly, and locate them more easily.

continuous integration merge their changes back to the main branch as often as possible. By doing so, you avoid the integration hell that usually happens when people wait for release day to merge their changes into the release branch.

Continuous Integration is cheap. Not integrating continuously is expensive. If you don’t follow a continuous approach, you’ll have longer periods between integrations. This makes it exponentially more difficult to find and fix problems. Such integration problems can easily knock a project off-schedule, or cause it to fail altogether

Continuous Integration brings multiple benefits to your organization:

• Say goodbye to long and tense integrations
• Increase visibility enabling greater communication
• Catch issues early and nip them in the bud
• Spend less time debugging and more time adding features
• Build a solid foundation
• Stop waiting to find out if your code’s going to work
• Reduce integration problems allowing you to deliver software more rapidly

SELECT * FROM news WHERE date < 24 hours

SELECT * FROM news WHERE date >= now() - INTERVAL 1 DAY;

php bin/magento dev:profiler:enable html

To fix this issue you need to increase the value of max_input_vars in php.ini file. By default, this value is set to 1000. You should set it to 5000 or 10000.

# php -r “phpinfo();” | grep max_input_vars
max_input_vars => 1000 => 1000

Incrase the value to 5000 in php.ini file

ALTER TABLE table_name ALTER COLUMN column_name SET DEFAULT 'VALUE';

Run the following command

git clone -b mybranch --single-branch git://sub.domain.com/repo.git

The following command saved my day.

 sudo yum-complete-transaction --cleanup-only

SET SQL_MODE='ALLOW_INVALID_DATES'

Done the above configuration change and that solved my problem temporarly.
