Loop

The Loop step repeats a set of steps once per item. On the canvas the loop is drawn as a
group containing the steps that repeat, so its scope is visible at a glance.

Configuration

Field	Notes
Input Type	How the loop is driven — For Each over a collection, While or Do While against a condition, Previous Step Value, or Multi Record File to iterate a file's records
Loop On	The collection or value being iterated
Type	The data type of each item, so later steps know its shape
Intely Storage File Path	The file to read, for a multi-record file loop
Field Delimiter	The delimiter of that file
Entry Offset	Rows to skip before the first record — used to step past a header
On Error	What happens when an iteration fails: Continue With Next Iteration, or Exit Loop
Run iterations in parallel	Process items concurrently rather than one at a time

Controlling the loop from inside

Step	Effect
Continue Loop	Skip the rest of this iteration, carry on with the next
Stop Loop	Leave the loop entirely

Notes

On Error is the setting that matters most. Left to exit, one malformed record ends the
batch; set to continue, the run completes and the failures are in the log.
Run iterations in parallel is faster but gives up ordering, and multiplies the load on
whatever each iteration calls. Leave it off when the downstream system is rate-limited or the
order of writes matters.
For very large files, splitting first with Split File is often better than
one long loop.
