CrackerSuperior opened a new issue #12754:
URL: https://github.com/apache/shardingsphere/issues/12754
In the official example, I am a little confused, the configuration file is
as follows:
``` yaml
schemaName: logic_db
rules:
- !SHARDING
tables:
t_order:
actualDataNodes: jdbc_${0..1}.t_order_${0..1}
t_order_item:
actualDataNodes: jdbc_${0..1}.t_order_item_${0..1}
keyGenerateStrategy:
column: item_id
keyGeneratorName: increment
t_config:
actualDataNodes: jdbc_${0..1}.t_config
t_user:
actualDataNodes: jdbc_0.t_user_${0..1}
tableStrategy:
standard:
shardingColumn: id
shardingAlgorithmName: table_inline
keyGenerateStrategy:
column: id
keyGeneratorName: reset_increment
autoTables:
t_order_auto:
actualDataSources: jdbc_0, jdbc_1
shardingStrategy:
standard:
shardingColumn: order_id
shardingAlgorithmName: mod
t_order_item_auto:
shardingStrategy:
standard:
shardingColumn: order_id
shardingAlgorithmName: mod
bindingTables:
- t_order,t_order_item
broadcastTables:
- t_config
defaultTableStrategy:
standard:
shardingColumn: order_id
shardingAlgorithmName: standard_test
defaultDatabaseStrategy:
standard:
shardingColumn: user_id
shardingAlgorithmName: standard_test
shardingAlgorithms:
standard_test:
type: STANDARD_TEST
table_inline:
type: INLINE
props:
algorithm-expression: t_user_${id % 2}
mod:
type: MOD
props:
sharding-count: 2
keyGenerators:
increment:
type: INCREMENT
reset_increment:
type: RESET_INCREMENT
```
I don't understand how this t_order uses t_order_auto. Does it just use name
recognition?
