faucet-source-redshift 1.3.0

#![cfg_attr(docsrs, feature(doc_cfg))]

//! # faucet-source-redshift
//!
//! Amazon Redshift query source connector for the faucet-stream ecosystem.
//!
//! Redshift is PostgreSQL wire-compatible, so this source connects through
//! `sqlx`'s Postgres driver, executes a configurable SQL query, and streams the
//! result rows as `serde_json::Value` records with `O(batch_size)` memory.
//! It supports full and incremental (bookmark-based) replication.
