Config Options
Vector Configs
m: Maximum number of connections each node can have at each layer of the graph (default 16)ef_construction: Size of dynamic list of candidates considered during vector insertion (default 128)ef_search: Size of the dynamic list of candidates maintained during the search process (default 768)
| Parameter | Effect | Higher Value | Lower Value |
|---|---|---|---|
m | Controls graph connectivity | Richly connected graph with better pathfinding but more memory | Sparse graph with faster construction but worse pathfinding |
ef_construction | Size of candidate list during indexing | High-quality, accurate index but more indexing time and memory | Faster indexing but can miss some connections & degrade recall |
ef_search | Candidate pool size during query | Wider search scope, improving recall and accuracy but slower search | Narrower search scope, faster search but more approximate results |
Graph Configs
secondary_indices: List of secondary indices for graph operations (default empty)
Database Configs
db_max_size_gb: The maximum size of the database in GB (default 10)mcp: Enable MCP support (default true)
