lingbin opened a new issue #2605: There is a memory leak when compression fails in ColumnWriter URL: https://github.com/apache/incubator-doris/issues/2605 A Page object is newed at L373 https://github.com/apache/incubator-doris/blob/3022955f32c9764fd2634d57faa14664212d1831/be/src/olap/rowset/segment_v2/column_writer.cpp#L369-L375 If we meet something wrong at L407, we will return directly, which causes a memory leak. Because this `Page` object cannot be added to the linked-list, and only the `Pages` in the linked-list can be destructed in the `ColumnWriter` dtor. https://github.com/apache/incubator-doris/blob/3022955f32c9764fd2634d57faa14664212d1831/be/src/olap/rowset/segment_v2/column_writer.cpp#L406-L408
