Where is the best place to store select values?

Question

Ruby on Rails

You need to fasten select with a search to select top level domains.
I tried to store options in a js file on the client side, but it weighs 40kb (about 1500 thousand elements in the collection), and it takes a long time to load.
Where is the best place to store the options list?
Perhaps in PostgreSQL or as a collection in the model and then load the AJAX request?

Answer 1

Perhaps in PostgreSQL or as a collection in the model and then load the AJAX request?

Instead of "or" should be "and". Store the data in the DBMS and load it in parts upon an AJAX request.
You can do this either on your own or using ready-made components such as Select2. To get a part of the list, the pagination components are used.
