Fields

query_memory_bytes: NonZeroUsize

Maximum tracked resident bytes owned by one query across all operators.

batch_rows: NonZeroUsize

Maximum row count in an executor-owned transfer batch.

batch_payload_bytes: NonZeroUsize

Maximum estimated resident bytes in an executor-owned transfer batch.

blocking_operator_bytes: NonZeroUsize

Maximum estimated bytes retained for blocking state, including sort, aggregation, deduplication, graph traversal state and selected top-K. Source reads use the shared query budget independently of this cap.

graph_expansion_budget: Option<GraphExpansionBudget>

Override the row and cumulative payload limits of each seeded expansion. Live allocations still obey the operator, batch and shared query budgets. None uses the optimizer’s seed-window-derived limits.

max_spill_bytes: NonZeroU64

Maximum cumulative serialized spill bytes, including merge passes.

max_spill_runs: NonZeroUsize

Maximum cumulative spill runs created, including merge passes.

max_total_spill_bytes: NonZeroU64

Maximum live spill bytes shared by all queries using the spill directory.

max_total_spill_runs: NonZeroUsize

Maximum live spill runs shared by all queries using the spill directory.

min_spill_free_bytes: NonZeroU64

Free space preserved on the filesystem containing the spill directory.

spill_free_space_probe_interval_bytes: NonZeroU64

Reserved bytes between filesystem free-space probes for one spill pool.

spill_orphan_grace_period: Duration

Minimum age before a spill file from an earlier process is removed.

spill_directory: PathBuf

Directory governed as one shared spill pool.
