Struct SqlTransformConfig 

pub struct SqlTransformConfig {
    pub query: String,
    pub relations: Vec<RelationSpec>,
    pub memory_limit: Option<String>,
    pub threads: Option<usize>,
}

Configuration for the sql transform.

Fields

query: String

The SQL statement. The page’s records are the relation batch. Must produce a result set; each result row becomes one output record.

relations: Vec<RelationSpec>

Reference relations loaded once at compile time and joinable by name.

memory_limit: Option<String>

Optional DuckDB memory_limit pragma (e.g. “1GB”). Default: DuckDB’s own.

threads: Option<usize>

Optional DuckDB threads pragma. Default: DuckDB’s own. Set to 1–2 for high-fan-out matrices to avoid CPU over-subscription across rows.

Trait Implementations

impl Clone for SqlTransformConfig

fn clone(&self) -> SqlTransformConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SqlTransformConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SqlTransformConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for SqlTransformConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for SqlTransformConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
