Crate rivet 

Rivet — CLI tool to export PostgreSQL and MySQL tables to Parquet/CSV files (local, S3, GCS) with tuning profiles, preflight diagnostics, chunked parallelism, retry logic, and SQLite-backed state tracking.

Not a stable public API

This crate (rivet-cli on crates.io) is a CLI product, not an embeddable library. The library target exists solely to support Rust’s integration test harness (tests/ requires a library to link against). Internal modules may change at any patch release without notice. See docs/adr/0002-cli-product-vs-library.md for the full decision.

Stable for integration tests: config, format, pipeline, resource, state. All other modules are pub(crate) and not reachable from external consumers.
