Industry for what type of databases? 100+ TB DBs are very common thing in the RDBMS world. Doesn't have to be TPC-C just some benchmark with reasonable dataset size. 2010 was 8 years ago in modern world an x86 box can have 8 CPUs with close to 200 physical cores 6TB RAM and even consumer grade SSDs can store 800 GB multiple times on a singe drive. Outside of very niche scenario why would I use distributed database if I am not sure it can handle scale that plain old RDBMs can handle? The interesting use case is dataset size that a plain RDBMs would not be able to handle.
