Expand description

A set of options for controlling the output of Explain implementations.

Fields§

§arity: bool

Show the number of columns.

§cardinality: bool

Show cardinality information.

§column_names: bool

Show inferred column names.

§join_impls: bool

Render implemented MIR Join nodes in a way which reflects the implementation.

§humanized_exprs: bool

Use inferred column names when rendering scalar and aggregate expressions.

§keys: bool

Show the sets of unique keys.

§linear_chains: bool

Restrict output trees to linear chains. Ignored if raw_plans is set.

§non_negative: bool

Show the non_negative in the explanation if it is supported by the backing IR.

§no_fast_path: bool

Show the slow path plan even if a fast path plan was created. Useful for debugging. Enforced if timing is set.

§no_notices: bool

Don’t print optimizer hints.

§node_ids: bool

Show node IDs in physical plans.

§raw_plans: bool

Don’t normalize plans before explaining them.

§raw_syntax: bool

Disable virtual syntax in the explanation.

§redacted: bool

Anonymize literals in the plan.

§subtree_size: bool

Show the subtree_size attribute in the explanation if it is supported by the backing IR.

§timing: bool

Print optimization timings.

§types: bool

Show the type attribute in the explanation.

§filter_pushdown: bool

Show MFP pushdown information.

§features: OptimizerFeatureOverrides

Optimizer feature flags.
