Alexander Kolbasov commented on HIVE-19902:
-------------------------------------------

[~owen.omalley] Thank you for the example - I didn't know about Level.Trial 
annotations. I'll experiment with JMH more using this approach. I still have 
other concerns with JMH since it doesn't give me full control over the results 
dataset. One feature that I am using a lot is saving raw data in files and 
looking at gnuplot graphs.

[~alangates] [~pvary] [~vihangk1] [~owen.omalley] I still think that the 
current approach (not using JMH) has its benefits - it is very simple and 
doesn't have any licensing issues. What do you think about going ahead with the 
current proposed implementation and then later possibly adding separate 
JMH-based submodule which isn't compiled by default?
