Concurrent Change in Marketo Field of same lead

[varunshrma]

Hi All,

I would like to understand the behaviour of the Marketo Field data commit. Suppose, Smart campaign is updating field f1 of lead L1 to value X in a flow. It is being used in the next steps of same flow. At the same time, Second different Smart Campaign of another program try to update same field f1 of same lead L1 in its flow.

Does Second Campaign able to modify the field f1 of lead L1 meanwhile flow of first smart campaign is not complete?
In short, Does the multiple CDV steps (DML transactions) are atomic in a flow of smart campaign.

Flows are not in any way comparable to SQL transactions. Individual Flow steps across all Smart Campaigns attempt to run in parallel.

Of course there are certain tasks that cannot truly run in parallel, such as updating the same column in the same row, but the order of serialization is not guaranteed to be the order in which the Flows started.
