Expand description

This encapsulates the spilling state

Fields§

§spill_expr: LexOrdering

Sorting expression for spilling batches

§spill_schema: SchemaRef

Schema for spilling batches

§merging_aggregate_arguments: Vec<Vec<Arc<dyn PhysicalExpr>>>

aggregate_arguments for merging spilled data

§merging_group_by: PhysicalGroupBy

GROUP BY expressions for merging spilled data

§spill_manager: SpillManager

Manages the process of spilling and reading back intermediate data

§spills: Vec<SortedSpillFile>

If data has previously been spilled, the locations of the spill files (in Arrow IPC format)

§is_stream_merging: bool

true when streaming merge is in progress

§peak_mem_used: Gauge

Peak memory used for buffered data. Calculated as sum of peak memory values across partitions
