Struct CompactFragReuseIndex 

pub struct CompactFragReuseIndex {
    pub uuid: Uuid,
    pub details: FragReuseIndexDetails,
    /* private fields */
}

A compact row-address remap chain for deferred compactions.

Each FRI version retains rewritten-row bitmaps and fragment layouts. Queries use bitmap rank plus the ordered new-fragment ranges instead of storing one hash-map entry per affected row.

Fields

uuid: Uuid

details: FragReuseIndexDetails

Implementations

impl CompactFragReuseIndex

pub fn try_new(uuid: Uuid, details: FragReuseIndexDetails) -> Result<Self>

Build a queryable index directly from serialized FRI details without expanding each affected row into a hash map.

pub fn row_addr_remap(&self) -> &RowAddrRemap

The ordered remap chain used by index and transaction remapping paths.

pub fn is_empty(&self) -> bool

Returns whether the index contains no row-address remapping.

pub fn remap_row_id(&self, row_id: u64) -> Option<u64>

pub fn remap_row_ids_in_place(&self, row_ids: &mut [Option<u64>])

Apply all FRI versions to row addresses in place. None values remain deleted and missing mappings pass through unchanged.

pub fn remap_row_addrs_tree_map( &self, row_addrs: &RowAddrTreeMap, ) -> RowAddrTreeMap

pub fn remap_row_ids_roaring_tree_map( &self, row_ids: &RoaringTreemap, ) -> RoaringTreemap

pub fn remap_row_ids_record_batch( &self, batch: RecordBatch, row_id_idx: usize, ) -> Result<RecordBatch>

Remap a record batch that contains a row_id column at index row_id_idx Currently this assumes there are only 2 columns in the schema, which is the case for all indexes. For example, for btree, the schema is (value, row_id). For vector index storage, the schema is (row_id, vector).

pub fn remap_row_ids_array(&self, array: ArrayRef) -> PrimitiveArray<UInt64Type>

pub fn remap_fragment_bitmap( &self, fragment_bitmap: &mut RoaringBitmap, ) -> Result<()>
