func NewConn(db sqlx.SqlConn, c cache.CacheConf, opts ...cache.Option) CachedConn

NewConn returns a CachedConn with a redis cluster cache.

func NewNodeConn

func NewNodeConn(db sqlx.SqlConn, rds *redis.Redis, opts ...cache.Option) CachedConn

NewNodeConn returns a CachedConn with a redis node cache.

func (CachedConn) DelCache
