Structs
A rule-based optimizer.
A standalone
OptimizerConfig that can be used independently
of DataFusion’s config managementEnums
If a rule is with
ApplyOrder, it means the optimizer will derive to handle children instead of
recursively handling in rule.
We just need handle a subtree pattern itself.Traits
Options to control the DataFusion Optimizer.
OptimizerRule transforms one [‘LogicalPlan’] into another which
computes the same results, but in a potentially more efficient
way. If there are no suitable transformations for the input plan,
the optimizer can simply return it as is.
