Fields

input_kind: String

Input kind passed to the Parquet reader.

remote_read_mode: String

Requested remote read mode, or none for non-remote reads.

backend: String

Parquet reader backend evidence.

backend_build_status: String

Build-time remote backend status reported by cudf/libcudf.

remote_bytes: Option<u64>

Remote bytes read, when reported by the lower layer.

remote_range_count: Option<u64>

Remote range count, when reported by the lower layer.

device_read_support: String

Direct device-read support evidence reported by the lower layer.

pruning_input_row_groups: Option<u64>

Row groups participating in this read after any caller row-group selection.

row_groups_after_stats_filter: Option<u64>

Row groups surviving libcudf statistics pruning, when a predicate was present.

row_groups_after_bloom_filter: Option<u64>

Row groups surviving libcudf Bloom-filter pruning, when a predicate was present.

bloom_pruning_status: String

Stable status explaining Bloom-pruning evidence or known ineligibility.
