Struct OLAP 

pub struct OLAP;

OLAP database engine for real-time analytical processing.

High-performance columnar OLAP database (olap-rust) with block-based storage, GraphQL API, and multi-user access control. Designed for real-time analytical queries on large datasets with caching, external data connector framework (spouts), and full-text search integration. Built with Rust, Tokio, Juniper/Async-GraphQL, Axum, and OpenTelemetry tracing.
