Comparison between polardb and mysql

The architecture is different and the performance is different.

1. Different architectures: PolarDB is a distributed relational database that uses a multi-copy shared storage architecture at the bottom, while MySQL is a traditional relational database that uses a disk-based storage architecture at the bottom.

2. Different performance: PolarDB’s multi-copy shared storage architecture can provide higher performance and faster response time, and also supports automatic expansion and contraction, while MySQL’s performance mainly depends on hardware configuration and database optimization.
