Struct FragReuseIndex 

pub struct FragReuseIndex {
    pub uuid: Uuid,
    pub row_id_maps: Vec<HashMap<u64, Option<u64>>>,
    pub details: FragReuseIndexDetails,
}

An index that stores row ID maps. A row ID map describes the mapping from old row address to new address after compactions. Each version contains the mapping for one round of compaction.

Fields

uuid: Uuid

row_id_maps: Vec<HashMap<u64, Option<u64>>>

details: FragReuseIndexDetails

Implementations

impl FragReuseIndex

pub fn new( uuid: Uuid, row_id_maps: Vec<HashMap<u64, Option<u64>>>, details: FragReuseIndexDetails, ) -> Self

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

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<()>

Trait Implementations

impl Clone for FragReuseIndex

fn clone(&self) -> FragReuseIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FragReuseIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DeepSizeOf for FragReuseIndex

fn deep_size_of_children(&self, cx: &mut Context) -> usize

fn deep_size_of(&self) -> usize

impl<'de> Deserialize<'de> for FragReuseIndex

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FragReuseIndex

impl PartialEq for FragReuseIndex

fn eq(&self, other: &FragReuseIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FragReuseIndex

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
