 - **Logical plan**: Similar to the AST/`planNode` tree described above, it represents the abstract (non-distributed) data flow through computation stages.
 - **Physical plan**: A physical plan is conceptually a mapping of the logical plan nodes to physical machines running `cockroach`. Logical plan nodes are replicated and specialized depending on the cluster topology. Like `planNodes` above, these components of the physical plan are scheduled and run on the cluster.
