Поддержка "Read your own writes" в MongoDB Базы данных и системы хранения
Senior kernel engineer.
Ability to "Read your own writes" is often taken for granted by application developers as it does not need special support in a single-server databases. In distributed databases to "read your own writes" a developer often needs to change the application logic to be sure that the written data has propagated from the node it was written to to the node its being read from.
In the coming release MongoDB adds Causal Consistency support which simplifies the task of "reading your own writes".
