Struct ValidationConfig 

pub struct ValidationConfig {
    pub max_query_depth: Option<u32>,
    pub max_query_complexity: Option<u32>,
    pub max_response_bytes: Option<u64>,
    pub max_page_size: Option<u32>,
}

Query validation limits (compiled from [validation] in fraiseql.toml).

Fields

max_query_depth: Option<u32>

Maximum allowed query nesting depth; DEFAULT_MAX_QUERY_DEPTH when unset.

max_query_complexity: Option<u32>

Maximum allowed query complexity score.

max_response_bytes: Option<u64>

Maximum bytes a single read may deliver, measured on the rows that come back.

max_query_depth and max_query_complexity score a document — they are the guard for fields resolved at runtime, where the work grows with the shape of the request. They say nothing about a read served from a materialised view, which is one row read whatever its nesting depth, and whose cost is the bytes those rows weigh.

That is the quantity this bounds, and it is the only one that means the same thing on every transport: a GraphQL document, a REST ?select=, a gRPC column read and an NDJSON export all end in rows, and none of them can be scored for size before the database has answered. So this is enforced on the delivered rows rather than on the request — resolved once at the read chokepoint, charged wherever the rows arrive.

A streamed read is cut at the frame that crosses the ceiling rather than being read to the end, so the bytes in the error are the running total at refusal, not the size of the whole answer.

None leaves reads unbounded by size, which is the previous behaviour.

max_page_size: Option<u32>

Maximum number of rows a top-level first/last/limit argument may request, guarding against unbounded-pagination denial of service (#421). When unset, the runtime default (1000) applies; set to a large value to raise the ceiling. The server also honours the FRAISEQL_MAX_PAGE_SIZE environment variable as an override.
