Struct DomainEngine 

pub struct DomainEngine;

Metadata-driven domain engine for complex data management.

Enterprise-grade domain engine providing GraphQL API for managing domains, entities, and attributes with dynamic expression evaluation and multi-source data aggregation. Features fine-grained permissions, multi-dimensional attributes, and connectivity to data sources (OLAP, PostgreSQL, ClickHouse). Built with Rust, Tokio, async-graphql, Axum, DataFusion (SQL frontend), and OpenTelemetry.
