transaction abort time. [#28662](https://github.com/apache/doris/pull/28662)
+

inverted index to accelerate `match_phrase` phrase
queries.[#37949](https://github.com/apache/doris/pull/37949)
+### Multi Catalog and Others

*/ * FROM t;`. [#37720](https://github.com/apache/doris/pull/37720)
+- Optimize JDBC Catalog refresh to reduce the frequency of client creation.
[#40261](https://github.com/apache/doris/pull/40261)

EmptySet，以减少不必要的数据扫描和计算。[#38135](https://github.com/apache/doris/pull/38135)
+
+- 提高 `ORDER BY` 全排序的性能。[#38985](https://github.com/apache/doris/pull/38985)
