Struct mz_compute::render::join::linear_join::LinearJoinSpec

source ·
pub struct LinearJoinSpec {
    implementation: LinearJoinImpl,
    yielding: YieldSpec,
}
Expand description

Specification of how linear joins are to be executed.

Note that currently yielding only affects the Materialize join implementation, as the DD join doesn’t allow configuring its yielding behavior. Merging #390 would fix this.
