PolarDB is interesting
Separation of Compute and Storage
Top layer, PolarProxy provides read-write separation and SQL acceleration functions.
In the middle layer,database engine node PolarDB has a multiple-read single-write (MRSW) database cluster
In the bottom layer, the distributed storage PolarStore provides multi-node shared storage for the top layer
PolarDB can be scaled out to a maximum of 16 nodes, and be scaled up to a maximum of 88 cores. The storage capacity is dynamically resized without additional configuration.
In short horizontal and vertical scaling
