What are the ways to quickly squeak the numbers you need?

Question

Programming

Hello, there is a site on the 1c-bitrix platform. When entering the site, the user selects an area to which stores are linked, and then compiles his basket. When changing the delivery area, the stores change, but the user needs to save the cart as much as possible (show available products and update the price for them). In one store there can be about 50-70 thousand products and it takes a very long time to compare, for example, 10 items from the basket with these 50 thousand barcodes or articles. Is there any way to speed up this process? As far as I know, there are special algorithms that allow you to speed up the search as much as possible. Who is familiar with them?

Answer 1

If you use Bitrix correctly, then it should work out of the box.
The editorial office "Business" is needed, separate warehouses are started, and the range of goods is started with the availability of these warehouses.
