> Hi Ioi, It looks good to me except the line 105 commented by Chris. I wonder how should this be tested to make sure there are no regressions. Do we really care about pre 1.4.2 formats? If so, what is the way to test it? We have a little lack of knowledge in this area. I guess, we need the performance team to get involved into this review. Thanks, Serguei

I am not sure about 1.4.2 formats. I guess we don't really care, but we should probably remove it in a separate RFE. I am trying to keep this PR from having any functional changes, and will just remove dead code.

For testing, I am running tiers 1-4. Will that be enough?

I'll ping the performance team.

Thanks
