### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description Currently, Apache Doris relies exclusively on dynamic partitions for data lifecycle management on aggregate model tables. Row-level TTL can help to improve query performance and reduce storage consumption. <img width="1280" height="883" alt="Image" src="https://github.com/user-attachments/assets/9fa9b320-dc12-46d4-bf95-cf086bb61d29"; /> ### Use case Row-level TTL targets scenarios that require data expiration based on non-partition columns. It is applicable to date-range partitioned tables, LIST partitioned tables, and non-partitioned tables. Row-level TTL can work either with or without when Dynamic Partitioning is enabled. Use Case: ```sql CREATE TABLE example_db.example_tbl ( k1 DATE, k2 INT, k3 SMALLINT, v1 VARCHAR(2048), v2 DATETIME DEFAULT "2014-02-04 15:36:00" ) PARTITION BY RANGE (k1) () DISTRIBUTED BY HASH(k2) BUCKETS 32 PROPERTIES( "function_column.ttl_col" = "v2", "function_column.ttl" = "3d" ); ``` ### Related issues _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.
