Fields

db_path: PathBuf

Path to the SQLite database file for vector metadata.

index_dir: PathBuf

Directory for HNSW index files and mmap vector files.

embedding_service_url: String

gRPC endpoint of the Python embedding service (e.g. "http://localhost:50051").

default_dimensions: usize

Default embedding dimensionality (384 = all-MiniLM-L6-v2).

ef_construction: usize

HNSW ef_construction build parameter (higher → better recall, slower build).

m_connections: usize

HNSW M connections parameter (higher → better recall, more memory).

ef_search: usize

HNSW ef search parameter (higher → better recall, slower search).

max_elements: usize

Maximum number of vectors per index.

cache_size: usize

Number of embedding LRU cache entries.

batch_size: usize

Maximum number of texts per embedding gRPC call.

embedding_timeout_ms: u64

Timeout for embedding gRPC calls in milliseconds.

num_threads: usize

Number of rayon threads for parallel index operations.

default_workspace_id: String

Default workspace id used when callers do not provide one explicitly.

require_workspace_id: bool

Require callers to provide workspace ids explicitly.

api_key_store_path: PathBuf

SQLite path for API key storage.

rate_limit_rps: u32

Default request budget per workspace in requests/second.

require_auth: bool

Require authentication for inbound API requests.
