Reynold Xin commented on SPARK-36913:
-------------------------------------
I'm actually a bit worried about adding stuff like this to Spark. There are so
many different types of indexes out there (and on top of that a lot of other
common database features, e.g. create primary key, foreign key, sequence
objects). Spark shouldn't and can't become a layer for doing database
management across all database features.
Are there concrete use cases for create index that we have seen?
