[Share]PolarDB- Separation of Compute Resources and Storage

More Posted time:Jan 7, 2019 22:20 PM

PolarDB is interesting
Good read------TL;DR

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
