分层可导航小世界 - O(log n) 搜索复杂度
AgentDB 自动构建 HNSW 索引:
const adapter = await createAgentDBAdapter({
dbPath: '.agentdb$vectors.db',
// HNSW 自动启用
});
// 使用 HNSW 搜索 (100µs vs 15ms 线性扫描)
const results = await adapter.retrieveWithReasoning(queryEmbedding, {
k: 10,
});
// 高级 HNSW 配置
const adapter = await createAgentDBAdapter({
dbPath: '.agentdb$vectors.db',

hnswEfConstruction: 200, // 构建质量 (默认:200)

Hierarchical Navigable Small World - O(log n) search complexity
AgentDB automatically builds HNSW indices:
const adapter = await createAgentDBAdapter({
dbPath: '.agentdb$vectors.db',
// HNSW automatically enabled
});
// Search with HNSW (100µs vs 15ms linear scan)
const results = await adapter.retrieveWithReasoning(queryEmbedding, {
k: 10,
});
// Advanced HNSW configuration
const adapter = await createAgentDBAdapter({
dbPath: '.agentdb$vectors.db',
hnswM: 16, // Connections per layer (default: 16)
hnswEfConstruction: 200, // Build quality (default: 200)
hnswEfSearch: 100, // Search quality (default: 100)
});
Parameter Tuning :
const adapter = await createAgentDBAdapter({
cacheSize: 1000, // Cache 1000 most-used patterns
});
// First retrieval: ~2ms (database)
// Subsequent: <1ms (cache hit)
const result = await adapter.retrieveWithReasoning(queryEmbedding, {
k: 10,
});
Cache Tuning :
// Cache automatically evicts least-recently-used patterns
// Most frequently accessed patterns stay in cache
// Monitor cache performance
const stats = await adapter.getStats();
console.log('Cache Hit Rate:', stats.cacheHitRate);
// Aim for >80% hit rate
// ❌ SLOW: Individual inserts
for (const doc of documents) {
await adapter.insertPattern({ /* ... */ }); // 1s for 100 docs
}
// ✅ FAST: Batch insert
const patterns = documents.map(doc => ({
id: '',
type: 'document',
domain: 'knowledge',
pattern_data: JSON.stringify({
embedding: doc.embedding,
text: doc.text,
}),
confidence: 1.0,
usage_count: 0,
success_count: 0,
created_at: Date.now(),
last_used: Date.now(),
}));
// Insert all at once (2ms for 100 docs)
for (const pattern of patterns) {
await adapter.insertPattern(pattern);
}
// Retrieve multiple queries efficiently
const queries = [queryEmbedding1, queryEmbedding2, queryEmbedding3];
// Parallel retrieval
const results = await Promise.all(
queries.map(q => adapter.retrieveWithReasoning(q, { k: 5 }))
);
// Enable automatic pattern consolidation
const result = await adapter.retrieveWithReasoning(queryEmbedding, {
domain: 'documents',

k: 10,

console.log('Optimizations:', result.optimizations);
