Пишем свою in-memory базу на Go, ускоряем поиск отелей в десятки раз

Если вы когда-либо строили высоконагруженные системы поиска, то знаете, что в какой-то момент узким местом становится не код, а сама архитектура. Поиск доступных отелей — как раз тот случай: миллиарды «ночей», десятки тысяч RPS, постоянные обновления календарей, строгая консистентность и высокая цена любой ошибки. Старый стек на Python + Postgres + Redis долго тянул, но однажды стал «тормозить» настолько, что оптимизировать дальше было невозможно — SQL-запросы разрастались, реплики множились, latency прыгала до 60 секунд, а кэширование превращалось в источник инцидентов. Так мы пришли к идее построить

I just heard that an old friend and colleague with whom I’d lost touch has died. There are lots of things to be said by people closer to them than I had become. But this person was kind, and classy, and creative. And by being all of that, they made the world, and so many other people’s lives, far better. If you know anyone like that, tell them so.

Gratitude Sunday 💚
I recently lost a dear friend and mentor to cancer, and it has reminded me how fragile and precious life is. Trying to slow down, be present, and appreciate the here and now a little more.
