### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version master (trunk) ### What's Wrong? The BE unit test `ColumnComplexTest.GetDataAtTest` fails with the following error: ``` be/test/core/block/column_complex_test.cpp:79: Failure Expected equality of these values: column_bitmap->get_data_at(0) Which is: \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0�q�PV\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0 column_bitmap_verify->get_data_at(0) Which is: \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0�q�PV\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0� QV\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0 ``` The `get_data_at()` method for `ColumnBitmap`, `ColumnHll`, and `ColumnQuantileState` returns raw binary data that includes uninitialized padding bytes, causing comparison failures even when the actual data values are equal. ### What You Expected? The test should pass — the bitmap/hll/quantile_state column data should compare equal when the logical values are the same. ### How to Reproduce? Run the BE unit test: ```bash bash run-be-ut.sh --run --filter=ColumnComplexTest.GetDataAtTest ``` ### 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.
