Trait SessionStateBuilderExt 

pub trait SessionStateBuilderExt {
    // Required method
    fn with_distributed_planner(self) -> Self;
}

Extension trait for SessionStateBuilder.

Required Methods

fn with_distributed_planner(self) -> Self

Injects a [QueryPlanner] implementation that attempts to distribute the plan after the normal planning passes are performed.

It will wrap the existing query planner if one, so while setting up DataFusion’s SessionStateBuilder, it’s important to inject the custom user query planner implementation with SessionStateBuilderExt::with_distributed_planner strictly before calling SessionStateBuilder::with_query_planner.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
