# Technical Summary Core engine built in Rust for performance; operates on a dataflow programming model where transformations are declarative formulas applied to input fields without mutation, enabling automatic data lineage tracking. Includes native connectors for sources (files, databases) and targets (vector DBs, graph DBs, Postgres) with standardized interfaces. Built-in incremental processing leverages Postgres to cache transformations and recompute only affected portions when source data or logic changes.
