<!-- Greeting --> Hey @alexander-bloss! I'm here to help you with any bugs, questions, or contributions you have. Let's work together to solve this issue. <!-- Answer --> To improve or optimize the behavior of the query `SELECT * FROM refs ORDER BY created_date desc` in the `refdiff_task_data.go` file, you should add an index on the `created_date` column. This will significantly speed up the sorting operation, especially given that the `refs` table has over 1GB of data. Here is how you can create an index on the `created_date` column: ```sql CREATE INDEX idx_created_date ON refs(created_date); ``` Adding this index will help the database engine to quickly locate and sort the rows based on the `created_date` column, thereby improving the performance of the query <sup>[[1]](https://github.com/apache/incubator-devlake/blob/main/backend/plugins/refdiff/tasks/refdiff_task_data.go)</sup>. Additionally, ensure that the `created_date` column is populated with data. If it is currently empty, you might need to update your data insertion logic to include values for this column <sup>[[2]](https://github.com/apache/incubator-devlake-website/blob/main/versioned_docs/version-v0.18/Configuration/images/domain_layer_model_v0.18.ndm2)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
