Implementations§

Source §

impl TransformationEngine

Source

pub fn new() -> Self

Source

pub async fn register_iceberg_catalog( &self, catalog_name: &str, catalog: Arc<dyn Catalog>, ) -> Result<()>

Registers an Apache Iceberg catalog directly into the DataFusion query context.

Source

pub async fn execute_sql(&self, sql: &str) -> Result<SendableRecordBatchStream>

Executes a SQL transform query against registered tables.

Source

pub async fn execute_dag( &self, dag: &ModelDag, project_dir: impl AsRef<Path>, output_dir: impl AsRef<Path>, ) -> Result<DagExecutionSummary>

Executes a full pipeline DAG tier by tier.

Before any model SQL runs, bronze sources declared in staging frontmatter are registered via register_bronze_sources_for_dag.

Blanket Implementations§

Source §

impl<T> Any for T
where T: 'static + ?Sized,

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

impl As for U

Source §

fn as_<T>(self) -> T
where T: CastFrom, U: Sized,

Casts self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_:: can be used in the same way as T as U for numeric conversions. Read more

where T: Any,

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Source §

fn type_name(&self) -> &'static str

Gets the type name of self

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

impl<T> BorrowMut<T> for T

Source §

impl<T> Downcast for T
where T: AsAny + ?Sized,

Source §

fn is<T>(&self) -> bool
where T: AsAny,

Returns true if the boxed type is the same as T. Read more

Source §

fn downcast_ref<T>(&self) -> Option<&T>
where T: AsAny,

Forward to the method defined on the type Any.

Source §

impl<T, U> Into for T
where U: From<T>,

Source §

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Source §

impl<T> IntoEither for T

Source §

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
