Struct LSMIndex 

pub struct LSMIndex { /* private fields */ }

Write-optimised vector index using LSM-tree tiered compaction.

Writes go to the MemTable; when full it flushes to level 0. Levels exceeding merge_threshold segments are compacted into the next level.

Implementations

impl LSMIndex

pub fn new(config: CompactionConfig) -> Self

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

Insert a vector. Auto-flushes and compacts as needed.

pub fn delete(&mut self, id: VectorId)

Mark a vector as deleted (tombstone).

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

Search across memtable and all levels, merging results.

pub fn compact(&mut self)

Manual compaction across all levels.

pub fn auto_compact(&mut self)

Auto-compact levels exceeding merge_threshold.

pub fn stats(&self) -> LSMStats

pub fn write_amplification(&self) -> f64
