ShardRouter

tdm_server_rust::db::shard

Struct ShardRouter 

Source 
pub struct ShardRouter { /* private fields */ }
Expand description

分片路由器

当前为单库实现：所有分片键都返回同一连接。多库分片时在此按 ShardKey::partition 选择目标库连接池。

Implementations§

Source§

impl ShardRouter

Source

pub fn single(primary: DbConn) -> Self

用单库连接构造路由器

Source

pub fn conn_for(&self, _key: ShardKey) -> &DbConn

按分片键取连接（当前恒返回单库连接）
