Module datafusion::physical_optimizer

This module contains a query optimizer that operates against a physical plan and applies rules to a physical plan, such as “Repartition”.

Modules

coalesce_batches	CoalesceBatches optimizer that groups batches together rows in bigger batches to avoid overhead with small batches
merge_exec	AddMergeExec adds MergeExec to merge plans with more partitions into one partition when the node needs a single partition
optimizer	Physical optimizer traits
repartition	Repartition optimizer that introduces repartition nodes to increase the level of parallism available
