Things to abuse on Yii2

I am new to Yii2 and PHP yet I am able delivered quality products to my clients. I’m planning to use this on my upcoming enterprise project. What I used on Yii2 is the GII,migration, widgets and MVC. Is there any other things or feature that I should be using on my new project? My new project will be focused on Big Data and High Traffic transactions.


[*]Eager loading

[*]REST (if your project is API based or single page application)


[*]Utilize available extensions (eg.kartik extensions)


Many more things available, that can be used based on requirements.
