Introduction

Sharding-Proxy is the second product of ShardingSphere. It defines itself as a transparent database proxy, providing a database server that encapsulates database binary protocol to support heterogeneous languages. Friendlier to DBA, the MySQL/PostgreSQL version provided now can use any kind of client access (such as MySQL Command Client, MySQL Workbench, etc.) that is compatible with MySQL protocol to operate data.

  • Totally transparent to applications, it can be used directly as MySQL/PostgreSQL.
  • Applicable to any kind of client end that is compatible with MySQL/PostgreSQL protocol.
