Teddy Choi commented on HIVE-16705:
-----------------------------------
The following Oracle & Intel's deck shows some simple lambdas with stream API
can be compiled into AVX2.

Also the benchmark I made shows that there's no significant performance
difference between a for loop and a lambda. I will update the numbers as soon
as possible.
