Let's talk about our history. How we started the project with a small vector database of less than 2 million records. Later, we received a request for +100 million records, then another +100... And so gradually we reached almost 1 billion. Standard tools were quickly running out of steam - we were running into performance, index size, and very limited resources. After a long series of trials and errors, we built our own low-cost cluster, which today stably processes thousands of queries to more than 1B vectors.

Why are modern frameworks once again trying to reinvent reactivity — and what do signals have to do with it? In this talk, we’ll take a look at signals as an attempt to give JavaScript developers fine-grained reactivity tools without extra code, proxies, or memoization. The problem they aim to solve is as old as frontend itself: how to update only what needs updating — and do it predictably. We’ll explore how this approach works, which frameworks have already adopted it, and what the current TC39 proposal means. Most importantly — do signals actually solve the problem, or are they just introducing a new layer of complexity with different syntax?

This talk is a lighthearted yet painfully familiar existential crisis of a frontend developer. We’ll start with simple DOM manipulation, walk through jQuery, SPA, React, and end with some thoughts on server-side rendering — with the help of a certain Twitter thread that turned out to be wiser than most textbooks.

This talk begins with a brief overview of frontend history, mentioning the era of AngularJS dominance and the reasons for its subsequent decline in popularity (particularly its complexity and the rise of React)
