I want to restrict the access of 100 termsets to 100 different users within same site collection. According to this thread, it seems the only choice is to setup 100 term groups with Term Store Administrator.
Is there any concern? We have 100 site collections on this SP2013 on-premise farm. Hence we may end up have total 10000 global term groups there. Any limitation on termset groups? Any better alternative? Thanks.
