Iterator

The iterator processor is used to process data cyclically. You can specify the number of iterations, conditions, or arrays.

Parameter	Description
Criteria	Specify the iteration criteria. Repeat Do While Foreach
Count	When Criteria is set to Repeat, configure the number of iterations. The default value is 3. A maximum of 100 iterations can be executed. Any access will trigger an error report.
Condition	When Criteria is set to Do While, configure the iteration conditions. When the conditions are met, a maximum of 100 iterations can be executed. Any access will trigger an error report.
Array	When Criteria is set to Foreach, configure the arrays to be iterated, which can be obtained from the preceding node. For details, see Referencing Variables. A maximum of 100 elements can be included in an array. Any access will trigger an error report.

Output variables

Parameter	Description
payload	Data that is traversed.
Loop size	Loop count.
Loop index	Index of the current loop, starting from 0.
Start time	Start time of node execution.
End time	End time of node execution.
Execution time	Node execution duration, in milliseconds.
