GraphQL server configuration

Fields

enable_introspection: bool

enable_playground: bool

max_query_depth: Option<usize>

max_query_complexity: Option<usize>

validation_config: ValidationConfig

enable_query_validation: bool

distributed_cache_config: Option<CacheConfig>

enable_sparql_field: bool

Whether the raw, unauthenticated SPARQL passthrough field (sparql(query: String!): String) is exposed in the schema at all. Disabled by default: it bypasses every GraphQL-level depth/complexity limit and lets any client run arbitrary SPARQL against the store, with no authentication or authorization of its own. Only enable this on a deployment where the GraphQL endpoint itself is already access-controlled.

sparql_query_timeout: Duration

Wall-clock timeout applied to each raw SPARQL passthrough query, only relevant when enable_sparql_field is true.

auto_generate_schema: bool

Whether to attempt automatic GraphQL schema generation from the RDF store’s vocabulary (rdfs:Class/owl:Class definitions) in addition to the built-in hello/version/triples/subjects/ predicates/objects fields. Falls back to the built-in fields alone when the store has no discoverable vocabulary, or when generation fails.

max_request_body_size: usize

Maximum accepted HTTP request body size, in bytes.

request_read_timeout: Duration

Idle/read timeout applied to each socket read while parsing an HTTP request (Slowloris protection).

max_connections: usize

Maximum number of concurrent HTTP connections served.

rate_limit_config: Option<RateLimitConfig>

Per-client-IP rate limiting configuration for incoming HTTP requests. Disabled by default (None): set this to enforce a request budget (token bucket / sliding window / fixed window / adaptive-under-load) before any GraphQL parsing/execution happens. See rate_limiting::RateLimiter.
