Перевоз данных по кусочкам: инженерная кухня SPQR
На связи Денис из команды SPQR . Мы занимаемся разработкой системы, которая помогает легко реализовать горизонтальное масштабирование PostgreSQL с помощью шардирования. И это не теоретическая задача на два шарда и десять таблиц. Необходимо сделать систему, которая в пределе хранит петабайты данных и выдерживает сотни тысяч запросов в секунду . В прошлой статье мы показывали SPQR со стороны пользователя: как выбрать ключ шардирования, как разложить таблицы на распределённые (distributed) и справочные (reference), как создать распределения и определить диапазоны ключей, а затем перевезти монолит на несколько шардов. Эта статья будет про инженерный путь: архитектуру, компромиссы и грабли, которые встретились по дороге.

SPQR в финтехе: реальная миграция на шардированную PostgreSQL-инсталляцию
На связи Денис Волков из команды платформы данных в Yandex Cloud. В предыдущей статье мы рассказали, как устроен SPQR (Stateless Postgres Query Router): архитектура, компоненты и принципы. Красивая теория. Эта статья — про то, что происходит, когда теорию начинаешь применять к живому продакшену с десятками таблиц, набором микросервисов и новогодней нагрузкой. Про грабли, решения и конечно же проблемы.

Correction: Serfs are able to nominate other "citizens" for the position of Tribunal (I talk about this more on my #UpScrolled account) but due to their unique position are totally ineligible for military service.
Obviously I'm not a fan of conscription but clearly the #Roman #spqr experience shows the folly of having a large standing army 🪖 which demands long periods of service -
Could (I'm not asking Should!) the Roman Empire have been saved? #SPQR Or even democratised?
The reforms by Emperor Diocletian and others were the start of the rot arguably at least
...
Perhaps with the provisio that: the second sons of all citizens should serve between 3-15 years in the legions or 4-20 years in the auxiliary legions , depending on family wealth, with Citizens able to volunteer for 18 years in return for tax exemptions and non citizens 20 years in return for citizenship.

Could (I'm not asking Should!) the Roman Empire have been saved? #SPQR made the Marian Reforms necessary in the first place
Could a mix of citizen-or Resident-conscription with serviceleadstorewards work?
Say allowing citizens to forgoe taxes in return for the old auxiliary 20-25 years of services? Or is it better to retain the "citizens can join the legions, non citizens can join the auxiliaries"?Perhaps with the provisio that: the second sons of all citizens should serve between 3-15

Making everyone a citizen seems laudable but it also exempted those citizens from taxation
The old system abandoned citizen conscription in favour of a volunteer based military which allowed non citizens to achieve citizenship via military service
What is ignored here is the divide between rich and poor which

#signal To add post‑quantum security, Signal introduced the Sparse Post‑Quantum Ratchet #SPQR , which runs alongside the existing #DoubleRatchet
The protocol now effectively combines three components: the symmetric ratchet, the classical DH ratchet, and the new post‑quantum ratchet (SPQR).

SPQR — наше опенсорс-решение для горизонтального масштабирования Postgres
В современных реалиях объёмы данных постоянно растут и появляются всё более жёсткие требования к производительности. Тут традиционный PostgreSQL сталкивается с фундаментальной проблемой: отсутствие нативной поддержки горизонтального масштабирования. Сегодня мы, команда платформы данных в Yandex Cloud, хотим рассказать о SPQR — нашем опенсорс‑инструменте, который который создавался как ответ на боль шардирования и эксплуатации крупных OLTP‑систем. Под катом — история о том, что стало отправной точкой для его создания, какие задачи он помогает решать, на чём основано наше решение и что помогает ему быть довольно простым в эксплуатации.

Seriously, @signalapp? You named your "triple ratchet" crypto #SPQR? Was "we love imperialism and anti-democratic militarism, thank you Open Technology Fund for funding us to help out the NSA" already taken as an acronym?!

Maailman käytetyin pikaviestinten salausprotokolla Signal Protocol vahvistui
Protokollaa uudistettiin ns. salauksen maailmanloppua ajatellen, eli kvanttilaskennan tuomia haasteita varten.
Signal Protocol on käytössä mm. Signalissa, WhatsAppissa sekä Androidin RCS-viesteissä.

#Signal Braces For #Quantum Age With #SPQR #Encryption Upgrade - Slashdot
Signal has introduced the #SparsePostQuantumRatchet (SPQR), a new upgrade to its #encryption protocol that mixes quantum safe #cryptography into its existing #DoubleRatchet. The result, which Signal calls the #TripleRatchet , makes it much harder for even future quantum computers to break private chats.
