function - flow - condition - map - eval - integration description: >- ## Node Types ### 1. `function` **Definition**: A **Hydra function node** used to provide a *subject* or perform a custom computation. It encapsulates reusable logic defined within the Hydra platform. ### 2. `flow` **Definition**: A node that **invokes another flow**, either **synchronously** or **asynchronously**, enabling flow modularization and reuse. ### 3. `condition` **Definition**: A **branching node** that evaluates a condition to determine the **flow of execution**, similar to `if`/`else` logic in programming. ### 4. `map` **Definition**: A **data transformation node** used to **reshape or remap the payload**, allowing the flow to adapt the structure of data as it progresses. ### 5. `eval` **Definition**: Executes **simple JavaScript code** to dynamically **evaluate expressions**, perform calculations, or manipulate data inline within the flow. ### 6. `integration` **Definition**: Similar to a `function` node, but specifically tied to **predefined APIs**. It uses an HTTP-like interface and references **a known set of external services** managed by the platform. subject: type: string description: Subject identifier for function or flow node types payload: description: Payload data for the node response_map: description: Mapping for response transformation options: $ref: '#/components/schemas/NodeOptions' await: type: boolean description: Whether to wait for completion nad return the result Edge: type: object required: - source - target properties: source: type: string description: ID of the source node target: type: string description: ID of the target node id: type: string description: Optional unique identifier for the edge sourceHandle: type: string description: Optional source handle identifier targetHandle: type: string description: Optional target handle identifier NodeOptions: type: object description: Node execution options properties: flat_map: type: boolean description: Whether to flatten the response backoff_ms: type: integer format: int64 description: >- Backoff duration in milliseconds - how long to wait before next attempt.
