Is it possible to execute frequent cached queries in yii2 db?

Question

Yii

It's about the yii2 cache.
let's have a method like this

function tags(){
return Tags::find()->where(['status'=>1])->all();
}

Now I will give 2 cases.
1) call tags() multiple times

echo count($class->tags())
foreach ($class->tags() as $tag){
...
}

2) assign some variable $tags = $class->tags()

echo count($tags)
foreach ($tags as $tag ){
...
}

The question is whether two different methods differ greatly in terms of server load, given that in the first case the request is cached.

Answer 1

What are cached queries in the database? There is a cache for this, so that these requests do not exist, and the data is taken from the cache!
Nobody does the way you try. Read about linked data and eager loading - the question, I think, will disappear.
