Spark SQL doesn’t support index :).

hi, guys, does Spark SQL support indexes?  if so, how can I create an index on my temp table? if not, how can I handle some specific queries on a very large table? it would iterate all the table even though all I want is just a small piece of that table.

great thanks,
