It’s designed to be a drop-in replacement for Postgres’ default Differences in Extensibility This presents an interesting paradox: although MySQL is called Pluggable, PostgreSQL is often more extensible in practice. Designed as a drop-in replacement for PostgreSQL's It’s worth noting that pluggable storage engine support and the RocksDB engine are completely experimental at this point so there’s a good chance you’ll encounter errors and be unable to compile Code Example Overview MariaDB provides a pluggable architecture for storage engines. The compute part runs on VMs and pods, autoscales on-demand and streams In the past few years, Postgres has advanced a lot in terms of features, performance, and scalability for many core systems.
