Module sqlite 

SQLite Backend for Experiment Storage (MLOPS-001)

Sovereign, local-first storage using SQLite with WAL mode.

Toyota Way: (Heijunka)

SQLite provides consistent, predictable performance without external dependencies.

Example

use entrenar::storage::{SqliteBackend, ExperimentStorage, RunStatus};

let backend = SqliteBackend::open("./experiments.db")?;
let exp_id = backend.create_experiment("my-exp", None)?;
let run_id = backend.create_run(&exp_id)?;
backend.log_metric(&run_id, "loss", 0, 0.5)?;

Module Organization

• backend - Core SqliteBackend struct and basic CRUD operations
• queries - Search, list, and parameter filtering methods
• metrics - Metric logging and retrieval (implements ExperimentStorage trait)
• artifacts - Artifact storage and retrieval
• types - Type definitions (ParameterValue, Experiment, Run, ArtifactRef)
