PrunerInner

mito2::read::pruner

Struct PrunerInner 

Source 
struct PrunerInner {
    num_workers: usize,
    file_entries: Vec<Mutex<FileBuilderEntry>>,
    stream_ctx: Arc<StreamContext>,
    manifest_pruned_files: Vec<AtomicBool>,
    static_manifest_kept_files: Vec<AtomicBool>,
    retain_builders: bool,
    enable_predicate_prefilter: bool,
}

Fields§

§num_workers: usize

Number of worker tasks.

§file_entries: Vec<Mutex<FileBuilderEntry>>

Per-file state (indexed by file_index).

§stream_ctx: Arc<StreamContext>

StreamContext containing all context needed for pruning.

§manifest_pruned_files: Vec<AtomicBool>

Positive manifest-prune cache shared across all scan partitions.

SAFETY: cached positives are valid because dynamic filters only tighten; dynamic negative decisions are not cached. Reset by add_partition_ranges() for each fresh batch of partition ranges.

§static_manifest_kept_files: Vec<AtomicBool>§retain_builders: bool

Keeps file range builders until the query-scoped pruner is dropped.

§enable_predicate_prefilter: bool

Whether FileRanges should execute the reduced-column predicate prefilter.

Implementations§

Source§

impl PrunerInner

Source

fn try_mark_manifest_pruned( &self, file_index: usize, reader_metrics: &mut ReaderMetrics, ) -> bool

Checks whether manifest-level pruning proves this file is empty given the current predicate. If true, CAS the shared cache from false→true and record files_time_range_pruned in reader_metrics.

Returns true if already cached or newly proven pruned.
