Habr<p>Как в Sidec благодаря exactly-once сократили потребление ресурсов без потери производительности</p><p>Меня зовут Сергей Гребенюк, я лидер разработки Sidec ( Росреестр ). Расскажу, как решили задачу объединения двух топиков с соотношением один ко многим и почему не устроило решение на Kafka-streams ( kafka docs ) и RocksDB ( github ). А также о том, как, опираясь на гарантии доставки exactly-once (EOS) ( confluent docs ), смогли снизить требования к ресурсам в несколько раз. На иллюстрации показаны два подхода к объединению топиков: с persistent cache и in-memory cache. Мы перейдём от первой схемы ко второй.</p><p><a href="https://habr.com/ru/companies/sberbank/articles/863688/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">habr.com/ru/companies/sberbank</span><span class="invisible">/articles/863688/</span></a></p><p><a href="https://zhub.link/tags/Sidec" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Sidec</span></a> <a href="https://zhub.link/tags/%D0%BF%D0%BE%D1%82%D1%80%D0%B5%D0%B1%D0%BB%D0%B5%D0%BD%D0%B8%D0%B5_%D1%80%D0%B5%D1%81%D1%83%D1%80%D1%81%D0%BE%D0%B2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>потребление_ресурсов</span></a> <a href="https://zhub.link/tags/kafkastreams" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>kafkastreams</span></a> <a href="https://zhub.link/tags/kafkaconnect" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>kafkaconnect</span></a></p>
