AgentDB Advanced Features

Enable QUIC synchronization by setting enableQUICSync to true, specifying a syncPort (default 4433), and listing peer addresses in syncPeers. Patterns replicate across all peers in under 1ms with TLS 1.3 encryption and automatic retry.

Use retrieveWithReasoning with a filters object supporting operators like $gte, $lte, $in, and $contains. You can also set hybridWeights to balance vector similarity against metadata match scores, such as 0.7 vector and 0.3 metadata.

Cosine similarity works best for text embeddings and semantic search, euclidean distance suits spatial data and image embeddings, and dot product is fastest for pre-normalized vectors. AgentDB supports all three via the metric parameter.

QUIC uses UDP, so verify your firewall allows UDP traffic on port 4433, for example with ufw allow 4433/udp. Confirm peers are reachable via ping and enable debug logging with DEBUG=agentdb:quic to diagnose connection failures.

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 different dbPath values per domain and route queries using a shard-key function. This supports horizontal scaling across knowledge, conversation, and code databases.
