vagetablechicken commented on issue #3307: UniqueRowsetIdGenerator may use a lot of memory
URL: https://github.com/apache/incubator-doris/issues/3307#issuecomment-613198701
https://github.com/apache/incubator-doris/blob/cc31bf9cf96ec0bef2ce55553b247df7bbe598e3/be/src/olap/rowset/unique_rowset_id_generator.cpp#L31
rowset_id is combined of version, inc_id, be_uid hi, be_uid lo. And the version and be_uid would never change. **So a inc_id corresponds to a RowsetId.**
We can use a bitmap to store inc_id.
