Fields§
§mode: OptimizeMode
The mode in which the optimizer runs.
replan: Option<GlobalId>
If the GlobalId
is set the optimizer works in “replan” mode.
This means that it will not consider catalog items (more specifically
indexes) with GlobalId
greater or equal than the one provided here.
enable_fast_path: bool
Enable fast path optimization.
enable_consolidate_after_union_negate: bool
Enable consolidation of unions that happen immediately after negate.
The refinement happens in the LIR ⇒ LIR phase.
persist_fast_path_limit: usize
An exclusive upper bound on the number of results we may return from a
Persist fast-path peek. Required by the create_fast_path_plan
call in
peek::Optimizer
.
enable_new_outer_join_lowering: bool
Bound from SystemVars::enable_new_outer_join_lowering
.
enable_eager_delta_joins: bool
Bound from SystemVars::enable_eager_delta_joins
.
enable_reduce_mfp_fusion: bool
Bound from SystemVars::enable_reduce_mfp_fusion
.
