Iterate

Splits an array into individual events. Each element becomes a separate downstream event.

Configuration

- iterate:
    name: split_records

Field	Type	Default	Description
`name`	string	required	Task name.
`iterate_key`	string		Key to extract the array from a JSON object. Without this, the entire event data is treated as an array.
`depends_on`	list		Upstream task names.
`retry`	object		Retry configuration.

Split entire event (event data is an array):

- iterate:
    name: split

Input: [{id: 1}, {id: 2}, {id: 3}] produces three separate events.

Extract and split a nested array:

- iterate:
    name: split_records
    iterate_key: records

Input: {total: 3, records: [{id: 1}, {id: 2}]} produces two events from the records array.
