Struct MemTable 

pub struct MemTable { /* private fields */ }

In-memory sorted write buffer backed by BTreeMap.

Implementations

impl MemTable

pub fn new(capacity: usize) -> Self

pub fn insert( &mut self, id: VectorId, vector: Option<Vec<f32>>, metadata: Option<HashMap<String, Value>>, seq: u64, ) -> bool

Insert/update. Returns true when full.

pub fn search(&self, query: &[f32], top_k: usize) -> Vec<SearchResult>

pub fn flush(&mut self, level: usize, fp_rate: f64) -> Segment

Flush to an immutable segment, clearing the memtable.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn is_full(&self) -> bool
