kangpinghuang commented on issue #1684: [Proposal] Bitmap Index File Format for V2 segment URL: https://github.com/apache/incubator-doris/issues/1684#issuecomment-526087487 > Agree. In this way the I/O cost of adding a new index is minimum, but reader now needs to know what indexes are available for this segment and the place of each index. Where do you think is the best place for such information? Perhaps in RowsetMetaPB? I think we can use TabletMetaPB's ColumnPB.is_bitmap_column to indicate whether has bitmap index for column in doris. But for segment itself, I have no idea where to put this field.
