map

pydantic model Map

Cardinality expansion

Given a node that emits 1 (iterable) event, split it into separate events.

`{admonition} Implementation Note Map is a *special node* - it is the only node where returning a list of values is interpreted as multiple events. For all other nodes, returning a list of values is interpreted as a single event with a list value. To return multiple events from a single node, chain a `map` after it. `
