The table catalog_product_link_attribute_int is huge in a couple of stores I have built.
A store with 1600 products has this table at 771MiB in which is over 10x the size of the next largest table. It makes the store awkward to backup or migrate and it can't be normal. On other sites it's usually around 50kb but on at least one other site it is over 700Mib.
Is this table safe to truncate? What does it actually do?
