## What it is
Supabase ETL is a high-performance Postgres logical replication engine written in Rust that performs initial table syncs and streams ongoing changes to built-in or custom destinations. It can be embedded as a Rust library or run as a standalone binary.

## Use cases
- replicate postgres tables to another destination in real time
- stream postgres changes to a data warehouse or data lake
- capture inserts, updates, deletes, and truncates via logical replication
- build a CDC pipeline from postgres to analytics or search systems
- embed postgres change capture in a rust application
- run a standalone postgres replicator binary

## When to choose
- you need high-performance, low-latency postgres change data capture in Rust
- you want a library you can embed in your own Rust service or a standalone replicator
- you need both initial table sync and ongoing replication in one tool

## When to avoid
- you need a fully stable, production-hardened tool - the project is under active development and APIs may change
- you want a no-code managed pipeline rather than running your own infrastructure
- your source database is not Postgres

## Facets
- artifact type: library
