[Question] rendering performance - optimal way to set/change/update only server changed parts of submission

[therabreal]

Hi,

We are dealing with large forms many components. Currently we set the submission for the complete form after each change/server interaction. This is starting to cause rendering performance issues for us.

Is there a way to update only part of the submission? So if the server only returns changed data - I would effectively like to merge this data with what is already in the form.

I could merge the existing submission with the changeset and then update the form but I guess this would "render" the data for entire form again?

Thanks in advance for any hints! RAB
