   Thanks @Jackie-Jiang . 
    Will the following approach be ok ?
   
   Compute min/max on demand in MutableNoDictColumnStatistics — when the 
mutable segment reports null (aggregated columns skip min/max tracking since 
the value mutates), scan the sealed forward index once (same pass isSorted() 
already does), before the BitSliced creator is constructed. 
   
   This adds one extra O(numDocs) scan per such column at seal time. Will this  
be OK?
