EachSequential

type: "io.kestra.core.tasks.flows.EachSequential"

For each value in the list, execute one or more tasks sequentially.

The list of tasks will be executed for each item sequentially. The value must be a valid JSON string representing an array, e.g. a list of strings ["value1", "value2"] or a list of dictionaries [{"key": "value1"}, {"key": "value2"}].

You can access the current iteration value using the variable null. The task list will be executed sequentially for each item.

We highly recommend triggering a subflow for each value. This allows much better scalability and modularity. Check the flow best practices documentation and the following Blueprint for more details.

Examples

id: "each_sequential"

    type: io.kestra.core.tasks.debugs.Return
    format: "{{ task.id }} with current value '{{ taskrun.value }}'"
