Expand description
Physical properties for physical plan nodes.
Describes the output characteristics of each physical operator: distribution, ordering, pipeline kind, parallelism, and memory policy. Used in the cost model, optimizer, and parallel execution planning.
Structs§
- Parallelism
- Parallelism constraints for this node.
- Physical
Properties - Physical plan properties attached to each node’s output.
- Sort
Order
Enums§
- Distribution
- Data distribution strategy for the output of a physical node.
- Memory
Policy - Memory policy for blocking/spill-capable operators.
- Ordering
- Output ordering guarantee.
- Pipeline
Kind - Whether the operator is streaming (produces incremental results) or blocking (must consume all input before producing output).
Constants§
- SPILL_
DEFAULT_ THRESHOLD - Default spill threshold for operators with full external spill support.
