# galaxy-io/filament

> Filament is a pluggable data replication system written in Go: it moves data from sources to sinks using full, incremental, or change data capture replication, with checkpointing, batching, and integrity verification. It targets data engineers who need a self-hosted ETL/ELT pipeline with an API, web UI, or an embeddable Go engine.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
