I am looking in the Magento database structure and found the
is_data_sharing field in the table
eav_entity_type. I want to know what the use of this field is.
I may be wrong, but I think for now it does nothing.
Maybe it's the start of a feature that didn't get implemented yet.
I've searched in the code for anything matching
isDataSharing and the only places where they show up are
is_data_sharingin the install/upgrade files from the eav module
isDataSharingjust in the annotations (getter and setter) in the Entity type model in the eav module.
