Sharding

Configuration Item Explanation

spring.shardingsphere.datasource.names= # Omit the data source configuration, please refer to the usage
# Standard sharding table configuration
spring.shardingsphere.rules.sharding.tables.<table-name>.actual-data-nodes= # Describe data source names and actual tables, delimiter as point, multiple data nodes separated with comma, support inline expression. Absent means sharding databases only.
# Databases sharding strategy, use default databases sharding strategy if absent. sharding strategy below can choose only one.
# For single sharding column scenario
spring.shardingsphere.rules.sharding.tables.<table-name>.database-strategy.standard.sharding-column= # Sharding column name
spring.shardingsphere.rules.sharding.tables.<table-name>.database-strategy.standard.sharding-algorithm-name= # Sharding algorithm name
# For multiple sharding columns scenario
spring.shardingsphere.rules.sharding.tables.<table-name>.database-strategy.complex.sharding-columns= # Sharding column names, multiple columns separated with comma
spring.shardingsphere.rules.sharding.tables.<table-name>.database-strategy.complex.sharding-algorithm-name= # Sharding algorithm name
# Sharding by hint
spring.shardingsphere.rules.sharding.tables.<table-name>.database-strategy.hint.sharding-algorithm-name= # Sharding algorithm name
# Tables sharding strategy, same as database sharding strategy

spring.shardingsphere.rules.sharding.auto-tables.<auto-table-name>.sharding-strategy.standard.sharding-algorithm= # Auto sharding algorithm name
# Key generator strategy configuration
spring.shardingsphere.rules.sharding.tables.<table-name>.key-generate-strategy.column= # Column name of key generator
spring.shardingsphere.rules.sharding.tables.<table-name>.key-generate-strategy.key-generator-name= # Key generator name

spring.shardingsphere.sharding.default-table-strategy.xxx= # Default strategy for table sharding
spring.shardingsphere.sharding.default-key-generate-strategy.xxx= # Default Key generator strategy
spring.shardingsphere.sharding.default-sharding-column= # Default sharding column name
# Sharding algorithm configuration
spring.shardingsphere.rules.sharding.sharding-algorithms.<sharding-algorithm-name>.type= # Sharding algorithm type
spring.shardingsphere.rules.sharding.sharding-algorithms.<sharding-algorithm-name>.props.xxx=# Sharding algorithm properties
# Key generate algorithm configuration
spring.shardingsphere.rules.sharding.key-generators.<key-generate-algorithm-name>.type= # Key generate algorithm type
spring.shardingsphere.rules.sharding.key-generators.<key-generate-algorithm-name>.props.xxx= # Key generate algorithm properties

Please refer to Built-in Sharding Algorithm List and Built-in Key Generate Algorithm List for more details about type of algorithm.

Attention

Inline expression identifier can use ${...} or $->{...}, but ${...} is conflict with spring placeholder of properties, so use $->{...} on spring environment is better.
