Support Single table query rewrite with out group by this is useful for complex filter or expresission. https://github.com/apache/doris/pull/35242 # Optimization 1. Estimate momory consumed by segment cache more accurately so that could release the unused memory more quickly. https://github.com/apache/doris/pull/35751 2. Filter empty partition before export table to remote storage.https://github.com/apache/doris/pull/35542 3. Optimize routine load task allocation algorithm to balance the load among Backends.https://github.com/apache/doris/pull/34778 # Bugfix 1. Fix datetime conversion error and data path error on Iceberg Table. The unit of the seventh parameter of ZonedDateTime.of is nanosecond, so we should multiply the microsecond by 1000. And when writing to a non-partitioned iceberg table, the data path has an extra slash. https://github.com/apache/doris/pull/35708 2. Fix query hang up if limited rows is reached on pipeline engine and memory is not released. https://github.com/apache/doris/pull/35746 3. Previously, irrelevant properties passed by users when using TVF were directly ignored by Doris. Now, we retain and pass these additional user-defined properties to the S3 SDK. https://github.com/apache/doris/pull/35515 4. BE coredump when enable decimal256 but fallback to old planner. When enable_decimal256 =true and falls back to the old optimizer, the sum result type become decimal128, but BE receives enable_decimal256=true, thinking that the sum result type is still decimal256. https://github.com/apache/doris/pull/35731 5. All DDL and DML will be forwarded to Master FE. And we forgot to set resource tag in ConnectionContext after forwarding.https://github.com/apache/doris/pull/35618 6. Fix variant with empty key will core problem. https://github.com/apache/doris/pull/35671 7. Fix partition mv rewrite result wrong. https://github.com/apache/doris/pull/35236 8. Restore table name is wrong when lower_case_table_names enabled. https://github.com/apache/doris/pull/35508 9. Bitmap and bloomfilter index should not do light index change. https://github.com/apache/doris/pull/35225 10. Fix BE memory info compatible with Cgroup in k8s env. https://github.com/apache/doris/pull/35425 11. Fix compatible problem with mysql workbench. Show Command should return an empty Set even if the result is empty. https://github.com/apache/doris/pull/35355 12. Doris occasionally encounters an issue where memory usage becomes exceptionally high and does not decrease. The leaked memory is occupied by Bloom filters stored in memory. https://github.com/apache/doris/pull/34871 ### Solution _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.
