Immutable point-in-time DataFusion scan metrics.

Fields

reader: DeltaReadMetricsSnapshot

Core reader planning and execution metrics.

use_view_types: bool

Whether the provider requested Arrow view arrays for string and binary data columns.

output_batch_size: Option<u64>

Effective DataFusion task batch size observed at execution.

dynamic_partition_files_pruned: u64

File tasks pruned before admission by a dynamic partition filter. A task is either a whole physical file or one independently read file range.

dynamic_partition_files_kept: u64

File tasks kept after consulting retained dynamic partition filters. A task is either a whole physical file or one independently read file range.

dynamic_filters_received: u64

Physical filters offered to the post-optimization hook.

dynamic_filters_accepted: u64

Offered filters retained for dynamic partition pruning.

dynamic_filters_unsupported: u64

Offered filters rejected by the dynamic partition policy.

dynamic_filter_snapshots: u64

Current dynamic expressions consulted during file admission.

dynamic_files_not_pruned_missing_metadata: u64

Kept file tasks with missing, invalid, or unparsable partition metadata.

dynamic_files_not_pruned_unsupported_expression: u64

Kept file tasks with unavailable, unsupported, or failed expressions.
