It only happens when enabled of course. I just wonder if we need to micro-optimize the loop below with something more performant if this is critical, but maybe it isn't. This is not a performance intensive path. This will execute during planning phase. Also the loop size is numBins, which is 254 by default. So I am not sure we need to micro-optimise the loop? -- This is an automated message from the Apache Git Service.
