### 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 we have to use Doris in [Lambda_architecture](https://en.wikipedia.org/wiki/Lambda_architecture), where historical data was loaded from ETL Jobs and realtime data was ingested by stream application into Doris. In most Lambda_architecture scenarios, historical data is not allowed to be modified because its accuracy. We need way to set historical partition to be immutable to prevent data from being modified by stream application which may produce old/expired data. The ideal solution in our case maybe: 1. create partition TEMP_T-1; 2. load HDFS data into TEMP_T-1 3. set TEMP_T-1 to be immutable 4. replace partition T-1 with TEMP_T-1, and now the T-1 partition will be immutable unless it's changed to mutable The above procedure requires the ability to set an partition to be immutable in Doris. I wonder if there is a better solution, thanks. ### Use case _No response_ ### 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.
