Parent article: Why Uber dropped PostgreSQL
That's one of the issues with the Uber article : there is a PostgreSQL setting preventing that issue :
https://www.postgresql.org/docs/current/static/hot-standb... => hot_standby_feedback.
https://www.postgresql.org/docs/current/static/hot-standb... => hot_standby_feedback.
The Uber article sadly lacks some crucial information, and fails to mention hot updates that prevent rewriting indexes, that feedback setting... With more information, it would be possible to better understand the issues they have, but it would be complicated for them to show their database schema I suppose.
