Review Comment:
   good catch. but I think this getColumnIndexes() is simply broken after adding the new index-spi support, which allows one to add new index types, not in this hard coded list of index types. Perhaps need to use `IndexService.getInstance().getAllIndexes()` to refactor this method.
   
   cc @gortiz who added index-spi support, to shed more light on this.
