如果您想在 ShardingSphere-Proxy 中使用 ShardingSphere 影子库功能请参考以下配置。
rules:
- !SHADOW
dataSources:
shadowDataSource:
productionDataSourceName: # 生产数据源名称
shadowDataSourceName: # 影子数据源名称
tables:
<table_name>:
dataSourceNames: # 影子表关联影子数据源名称列表
- <shadow_data_source>
shadowAlgorithmNames: # 影子表关联影子算法名称列表
- <shadow_algorithm_name>
defaultShadowAlgorithmName: # 默认影子算法名称(选配项)
shadowAlgorithms:
<shadow_algorithm_name> (+): # 影子算法名称
type: # 影子算法类型
props: # 影子算法属性配置
详情请参见内置影子算法列表
