What is Chunk and Cursor?

 What is Chunk and Cursor?

Chunk: It will “paginate” your query, this way you use less memory.
* Uses less memory
* It takes longer
public function getData() {
    Contact::chunk(1000, function ($contacts) {
        foreach ($contacts as $contact) {
            //rest of your code...
        }
    });
}

Cursor: You will use PHP Generators to search your query items one by one.

* It takes less time
* Uses more memory
public function getData() {
    foreach (Contact::cursor() as $contact) {
        //rest of your code...
    }
}
