you could config A as defaultDataSource,and config tb_config as the broadcast table for the other four databases.like this:
```yaml
dataSources:
names: ds0,ds1,ds2,ds3,de4
ds0:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/A
username: root
password:
ds1:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:13306/B1
username: root
password:
ds2:
url: jdbc:mysql://localhost:23306/B2
ds3:
url: jdbc:mysql://localhost:33306/B3
ds4:
url: jdbc:mysql://localhost:43306/B4
sharding:
default-database-strategy:
inline:
sharding-column: id
algorithm-expression: ds$->{id % 2}
default-table-strategy:
inline:
sharding-column: age
algorithm-expression: user_$->{age % 2}
tables:
user:
# Configuration rules are not included database A
actual-data-nodes: ds$->{1..4}.user_$->{1..4}
default-data-source-name: ds0
broadcast-tables: t_config
```
