morningman opened a new issue #7854: URL: https://github.com/apache/incubator-doris/issues/7854
### 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. ### Version 0.15 ### What's Wrong? BE crash with assertion failure: `index size is larger than char size, index=10 , char=4` at `encode_ascending()` of `be/src/olap/key_coder.h` ### What You Expected? works well ### How to Reproduce? This happens when writing short key index. And the column is defined as `char(10)`, but the value is only 4 bytes long. So make the assertion failed. Still don't know why, a tmp solution is: ``` - CHECK(index_size <= slice->size) - << "index size is larger than char size, index=" << index_size - << ", char=" << slice->size; - buf->append(slice->data, index_size); + if (index_size > slice->size) { + LOG(WARNING) << "index size is larger than char size, index=" << index_size + << ", char=" << slice->size << ", slice: #" << slice->to_string() << "#"; + char new_buf[index_size]; + memset(new_buf, 0, sizeof(new_buf)); + memcpy(new_buf, slice->data, slice->size); + buf->append(new_buf, index_size); + } else { + buf->append(slice->data, index_size); + } } ``` Not sure if it has side affect. ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] 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.
