wangbo opened a new issue #8388: URL: https://github.com/apache/incubator-doris/issues/8388
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Description When a query hits index, then index bitmap is reset; Storage layer read rows by index bitmap. In the current implementation, even a query doesn't hit any index, storage still need to read rows by index bitmap. This could bring two costs: 1 Read data from roaring bitmap. 2 The foreach to read rowids from roaring bitmap. There is still optimization room for query without indexes. ### Solution _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
