Struct SparseTableSpec 

pub struct SparseTableSpec {
    pub table: &'static str,
    pub identity_cols: &'static [&'static str],
    pub scope_col: Option<&'static str>,
}

稀疏、非 SQL 存储适配器使用的表身份描述。

具体表名由业务模块提供；平台驱动只据此建立通用索引，不依赖业务类型或解析 DDL。

Fields

table: &'static str

identity_cols: &'static [&'static str]

scope_col: Option<&'static str>
