 * `DocumentWriter`: Lets you persist the Documents into a database (most commonly in the AI stack, a vector database).

 == Function Calling
 
 Large Language Models (LLMs) are frozen after training, leading to stale knowledge and they are unable to access or modify external data.
 
+image::function-calling-basic-flow.jpg[Function calling, width=800, align="center"]

 The `Function Calling` mechanism addresses these shortcomings.
 It allows you to register your own functions to connect the large language models to the APIs of external systems.
 These systems can provide LLMs with real-time data and perform data processing actions on their behalf.
