chaoyli commented on issue #2949: add rle v2 encoding for segment v2 URL: https://github.com/apache/incubator-doris/pull/2949#issuecomment-588286553 If you just move the old code from the AlphaRowset, the question of AlphaRowset still exists. Like - I/O exemplification of read StreamHead. - Two much virtual functions of read caused by streaming read of ORC. - Not import ORCFile the latest enhancement in recent years. This are all questions we start to build SegmentV2.
