Expand description

Execution policy copied into admitted native query contexts.

Fields§

§lakehouse_cache_fill: LakehouseCacheFillConfig

Lakehouse cache-fill policy and shared resource limits.

§source_storage_profiles: Vec<SourceStorageProfile>

Source object-store profiles available to service-owned execution contexts.

§source_scheduler_policy: SourceSchedulerPolicy

Bounded source scheduling policy copied into admitted contexts.

§source_chunk_planning_mode: SourceChunkPlanningMode

Source chunk planning mode copied into admitted contexts.

§statistical_aggregate_execution_mode: StatisticalAggregateExecutionMode

Floating statistical aggregate execution contract copied into admitted contexts.

§planning_policy: PlanningPolicy

Join and dynamic-filter thresholds copied into admitted contexts; a plan decided without an admission artifact is admitted under it.

§aggregate_strategy_execution_options: AggregateStrategyExecutionOptions

Grouped aggregate strategy execution policy copied into admitted contexts.

§source_chunk_planning_options: SourceChunkPlanningOptions

Expert local-throughput source chunk planning policy copied into admitted contexts.

§max_source_chunk_bytes: u64

Source chunk byte target copied into admitted bounded contexts. u64::MAX derives a finite target from the immutable grant.

§max_row_groups_per_chunk: usize

Source row-group target copied into admitted bounded contexts.

§max_retry_attempts: usize

Bounded retry-attempt cap copied into admitted bounded contexts.

§min_retry_chunk_row_groups: usize

Bounded retry row-group floor copied into admitted bounded contexts.
