Laljo John Pullokkaran commented on HIVE-10526:
-----------------------------------------------
I am not sure about that. We are trying to say if Latency (CPU + IO) is less
than epsilon and if row count difference is less than epsilon.
By separating CPU, IO we may loose the additive effect.
> CBO (Calcite Return Path): HiveCost epsilon comparison should take row count
> in to account
