purpose of Mosaic Dataset Item Cache (not Tile Cache)

Hello,

 

Can someone please explain the purpose of the Mosaic Dataset Item Cache?

https://pro.arcgis.com/en/pro-app/tool-reference/data-management/build-mosaic-dataset-item-cache.htm

 

The Usage mentions that it adds a function to the chain, okay, but it also creates another folder of images. These images seem to be extremely similar to the Pyramids and the Overviews.

 

Where does the Item Cache come into play when data is requested?

Is it completely redundant if I've already built Pyramids and Overviews?

 

Thanks,
