Flexible adaptation of database protocol, SQL dialect and database storage. It can quickly link applications and multi‐mode heterogeneous databases quickly. • Enhance: Capture database access entry to provide MySQL or PostgreSQL protocol to operate data, which is friendlier to DBAs • Transparent towards applications, it can be used directly as MySQL and PostgreSQL servers. • Applicable to any kind of terminal distributed data‐access applications with the databases. Focusing on interaction, it effectively organizes the interaction between messy applications and databases. The applications and databases that use

Workbench, etc.) that is compatible of MySQL protocol to operate data. • Totally transparent to applications, it can be used directly as MySQL. • Applicable to any kind of terminal that is compatible with the database. Focusing on interaction, it effectively organizes the interaction between messy applications and the database. The application and database that use Database Mesh to visit database will SQL does not have sharding conditions, it is impossible to shard without full route. In some applications, sharding conditions are not in SQL but in external business logic. So it requires to designate

application server is responsible to manage the connection life cycle. It is generally used with the Web Applications. dataSource tag It is used to configure the connection properties of the database, such as driver-name connection for every database operation. It is a bit slower and generally used for the simple applications. POOLED − For the dataSource type POOLED, MyBatis will maintain a database connection pool. And
