Crate semstrait 

semstrait

Compile semantic models to Substrait compute plans.

semstrait transforms YAML-based semantic model definitions into Substrait compute plans, enabling engine-agnostic analytics.

Planned Usage

use semstrait::{Schema, Query, emit_plan};

let schema = Schema::from_file("model.yaml")?;
let query = Query::new("sales")
    .rows(["dates.year", "markets.country"])
    .metrics(["revenue", "quantity"]);

let plan = emit_plan(&schema, &query)?;
// Execute on DataFusion, DuckDB, or any Substrait consumer
