### 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 master release-24.1.0 ### What's Wrong? When the flush thread pushes a buffer to the `flushQueue` but has not yet removed it from the `bufferMap`, the processing thread may retrieve the buffer that has already been pushed to the `flushQueue`. This results in the buffer not being in a read-only state. If, at this point, the import thread executes `drainTo` to retrieve the non-read-only buffer and performs a merge operation, a thread-safety issue may arise because of the buffer is `LinkedList`. This could lead to an` ArrayIndexOutOfBoundsException` or result in data loss.  ### What You Expected? Let`putRecordToFlushQueue(buffer); bufferMap.remove(bufferKey)` is a transactional operation ### How to Reproduce? When the flush thread pushes a buffer to the `flushQueue` but has not yet removed it from the `bufferMap`, the processing thread may retrieve the buffer that has already been pushed to the `flushQueue`. This results in the buffer not being in a read-only state. If, at this point, the import thread executes `drainTo` to retrieve the non-read-only buffer and performs a merge operation, a thread-safety issue may arise because of the buffer is `LinkedList`. This could lead to an` ArrayIndexOutOfBoundsException` or result in data loss. ### Anything Else? _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.
