# Better to implement it in CQL so we're not adding Thrift dependencies.
# I still think this is low priority since for non-toy datasets, there will be multiple splits
per vnode anyway.

> CASSANDRA-6084 shows there are some issues during running hadoop/pig job if vnodes are
enable. Also the hadoop performance of vnode enabled nodes  are bad for there are so many
splits.
> The idea is to combine vnode splits into a big sudo splits so it work like vnode is disable
for hadoop/pig job
