Firstly I Have More than 1 Million Data In my database , while i want to perform aggregation or annotation or filter it took huge time , i have to show all data at a time,,, i use select_related() for foreign key but i want to optimize database hitting , like i want to fetch all data from database in first database hit and convert them into dictionary or list and perform another queries into dictionary or list without hitting database i hope it can optimize database hit Example : In Laravel I Fetch All data from database and convert it into Array while i have to perform queries into it i convert them into collect() and perform queries , and it dont hit the database .
[a link ]:(https://laravel.com/docs/5.8/collections) !

I Can perform this in Django ???
