 In OpenObserve, functions are VRL (Vector Remap Language) scripts that transform your stream data. You create and manage functions via the OpenObserve UI or API. In the UI, go to **Pipelines > Functions** to open a built-in editor where you can write, test, and save VRL code. Once saved, a function can be associated with a stream so it runs on incoming data at ingest time.
