> Today the ColumnStats keys are in IndexID formats. These are hash IDs from column name, partition name, file name. For the query integration, when we do aggregate query, we need to return the file name part that contain the ranges. There are two ways of solving this
>  # We can store the file name directly in the key for now
>  # Add reverse lookup from FileIndexID to FileName
