15//! Define all property of plan tree node, which actually represent property of the node's result.
16//!
17//! We have physical property [`Order`] and [`Distribution`] which is on batch or stream operator,
18//! also, we have logical property which all [`PlanNode`][PlanNode] has.
19//!
20//! We have not give any common abstract trait for the property yet. They are not so much and we
21//! don't need get a common behavior now. we can treat them as different traits of the
22//! [`PlanNode`][PlanNode] now and refactor them when our optimizer need more
23//! (such as an optimizer based on the Volcano/Cascades model).
24//!
25//! [PlanNode]: super::plan_node::PlanNode
