   The `_paddedStrings` should not be setup in normal case (it's for 
backward-compatibility for some very old segment format). The map is used for 
looking up dict id, which is used for filtering phase (less frequently called 
comparing to read value from dict id).
   After a second thought, I feel adding this on-heap array to the default 
dictionary can potentially cause problems. Say a server has 10K segments 
loaded, each segment has one 10M string dictionary, it could consume 100G heap 
memory in the worst case
