Vectors are the New JSON in Postgres — When the popularity of JSON as an interchange format was rocketing and everyone and their dog was building a document oriented database, Postgres wisely added native JSON support and gradually introduced powerful ways to work with it.

Replacing Apache Hive, Elasticsearch and Postgres with Apache Doris — I can’t see an article about replacing Postgres with a Java-based MySQL-compatible database going down well here, but in the interests of fairness.. 😆 Plus it's called Doris, which is fantastic.
