В Яндекс Метрике существует сборка визитов пользователей на сайте, для которой нужно хранить историю всех событий и склеивать их друг с другом на лету. Для этого использовалась конвейерная распределенная система со своим самописным локальным хранилищем и логикой репликации и шардирования. По мере роста нагрузки мы уперлись в производительность отдельного шарда, при этом продолжать наращивать количество шардов без принципиальной перестройки архитектуры было крайне болезненно. |
