How to bulk apply an action/function to all existing objects

Just wanted to check whether there’s any good way to apply a function/action to a large (~500k) amount of objects?

We have quite a few cases where we want to add a new property to an ontology object, and be able to backfill that property on all marketplace installations of that property easily.

We’ve avoided this for the most part but can we do something like object table select all → apply action or retroactively apply an automate?

Any chance you can use the “Automate” App on Foundry. It should be able to bulk-apply actions to objects?!

An action can be applied to multiple objects by toggling “Allow multiple values” in the object reference parameter. Then in Workshop, an Object Table can use “enable multi-select”, which creates checkboxes for each row and a “Select all” checkbox in the table headers row. These selected objects can then be collectively passed to the action.

I don’t know if there is a limit to the number of objects that can be modified by an action.
