AgentDB Advanced Features

Enable QUIC synchronization by setting enableQUICSync to true and providing syncPort and syncPeers in the adapter configuration. Patterns replicate across all peers with sub-millisecond latency using multiplexed UDP streams with TLS 1.3 encryption.

Pass a filters object alongside the query embedding in retrieveWithReasoning, using operators like $gte, $lte, $in, and $contains. You can also set hybridWeights to balance vector similarity against metadata match scores.

Use cosine similarity for text embeddings and semantic search, euclidean distance for spatial or image data where magnitude matters, and dot product for pre-normalized vectors needing fast computation. Custom weighted distance functions are also supported.

QUIC sync commonly fails when firewalls block UDP traffic on the sync port. Allow UDP port 4433, verify peers are reachable via ping, and enable debug logging with DEBUG=agentdb:quic to diagnose connection issues.

Enable Maximal Marginal Relevance by setting useMMR to true and tuning mmrLambda between 0 and 1. A value of 0.5 balances relevance and diversity, while higher values prioritize diverse, non-redundant results.

Yes, create separate adapter instances with distinct dbPath values per domain and route queries using a shard-key function. This supports horizontal scaling by distributing patterns across domain-specific database files.
