# Configuration Sections

+ `Global config:` General configurations
+ `Data sources config:` Configures the instances of the upstream and downstream databases
+ `Routes:` Rules for upstream multiple schema names to match downstream single schema names (optional)
+ `Task config:` Configures the tables for checking
+ `Table config:` Configurations for specific tables (optional)

-------------------------------------------------
You need to specify these configurations in the configuration files.

`Global config`: General configurations, such as number of threads to check, whether to export `SQL` statement to fix inconsistent tables, and whether to campare the data.

`Data sources config: Configures the instances of the upstream and downstream databases.

`Routes`: Rules for upstream multiple schema names to match downstream single schema names (optional).

`Task config`: Configures the tables for checking. If some tables have a certain mapping relationship between the upstream and downstream databases or have some special requirements, you must configure these tables.

`Table config`: Special configurations for specific tables, such as specified ranges and columns to be ignored (optional).
